Redness on stomach
Gastritis | Cedars-Sinai
ABOUT CAUSES DIAGNOSIS TREATMENT NEXT STEPS
What is gastritis?
Gastritis is when your stomach lining gets red and swollen (inflamed).
Your stomach lining is strong. In most cases, acid does not hurt it. But it can get inflamed and irritated if you drink too much alcohol, eat spicy foods, have damage from pain relievers called NSAIDs, or smoke.
What causes gastritis?
Gastritis may be caused by many things. It can be caused by diet and lifestyle habits such as:
- Drinking too much alcohol
- Eating spicy foods
- Smoking
- Extreme stress. This can be from serious or life-threatening health problems.
- Long-term use of aspirin and over-the-counter pain and fever medicines
Health issues that can lead to gastritis include:
- Infections caused by bacteria and viruses
- Major surgery
- Traumatic injury or burns
Some diseases can also cause gastritis. These include:
- Autoimmune disorders. This is when your immune system attacks your body’s healthy cells by mistake.
- Chronic bile reflux. This is when bile backs up into your stomach and food pipe (esophagus). Bile is a fluid that helps you digest food.
- Pernicious anemia . This is a form of anemia that happens when your stomach can;t digest vitamin B-12.
What are the symptoms of gastritis?
Each person’s symptoms may vary. The most common symptoms of gastritis include:
- Stomach upset or pain
- Belching and hiccups
- Belly (abdominal) bleeding
- Nausea and vomiting
- Feeling of fullness or burning in your stomach
- Loss of appetite
- Blood in your vomit or stool. This is a sign that your stomach lining may be bleeding.
The symptoms of gastritis may look like other health problems. Always see your healthcare provider for a diagnosis.
How is gastritis diagnosed?
Your healthcare provider will give you a physical exam and ask about your past health. You may also have tests including:
- Upper GI (gastrointestinal) series or barium swallow. This X-ray checks the organs of the top part of your digestive system. It checks the esophagus, stomach, and the first part of your small intestine (duodenum). You will swallow a metallic fluid called barium. Barium coats the organs so that they can be seen on the X-ray.
- Upper endoscopy (EGD. This test looks at the inside of your esophagus, stomach, and duodenum. It uses a thin, lighted tube, called an endoscope. The tube has a camera at one end. Your healthcare provider puts the tube into your mouth and throat. Then the provider moves it into your esophagus, stomach, and duodenum. Your provider can see the inside of these organs. He or she can also take a small tissue sample (biopsy) if needed.
- Blood tests. You will have a test for H. pylori, a type of bacteria that may be in your stomach. Another test will check for anemia. You can get anemia when you don’t have enough red blood cells. Sometimes you may have low levels of certain vitamins and need to take a dietary supplements.
- Stool sample . This test checks to see if you have stomach bacteria that can cause gastritis. A small sample of your stool is collected and sent to a lab. Another stool test can check for blood in your stool. This may be a sign of gastritis if you have bleeding.
- Breath test. You may have a test where your breath is collected and analyzed for a stomach bacteria.
How is gastritis treated?
Treatment will depend on your symptoms, age, and general health. It will also depend on how severe the condition is.
In most cases, you will be given antacids and other medicines to reduce your stomach acid. This will help ease your symptoms and heal your stomach lining.
If your gastritis is caused by an illness or infection, your provider will also treat that health problem.
If your gastritis is caused by the H. pylori bacteria, you will be given medicines to help kill the bacteria. In most cases, you will take more than 1 antibiotic and a proton pump inhibitor. A PPI is medicine that reduces the amount of acid in your stomach. You may also be given a medicine for diarrhea.
Don't have any foods, drinks, or medicines that cause symptoms or irritate your stomach. If you smoke, it is best to quit. If you take aspirin or NSAIDs often, talk with your healthcare provider about other options.
What are possible complications of gastritis?
Chronic gastritis hurts your stomach lining. It can raise your risk for other health problems. These include:
- Peptic ulcer disease. This causes painful sores in your upper digestive tract.
- Gastric polyps. These are small masses of cells that form on the inside lining of your stomach.
- Stomach tumors. These can be cancer or not cancer (benign).
You may also get atrophic gastritis. This can happen if your gastritis is caused by the H. pylori bacteria or by an autoimmune disorder. Atrophic gastritis destroys the stomach lining cells that make your digestive juices. This raises your risk for getting stomach cancer. It can also cause low levels of certain vitamins in your blood.
Can gastritis be prevented?
Experts don’t know to stop gastritis from happening. But you may lower your risk of getting the disease by:
- Having good hygiene habits, especially washing your hands. This can keep you from getting the H. pylori bacteria.
- Not eating or drinking things that can irritate your stomach lining. This includes alcohol, caffeine, and spicy foods.
- Not taking medicines such as aspirin and over-the-counter pain and fever medicines. These include NSAIDs (nonsteroidal anti-inflammatory medicines.
When should I call my healthcare provider?
Call your healthcare provider if your symptoms get worse or if you have new symptoms. Call right away if you have bloody vomit, blood in your stools, or black, tarry-looking stools.
Key points about gastritis

Rash on Stomach: Symptoms, Causes, and Treatment
Skin rashes can be uncomfortable, causing patches of itchy, irritated, red, and swollen skin.
Rashes can form on any part of the skin, including the stomach.
In some cases, it’s easy to identify the cause of your stomach rash, like when you accidentally come into contact with poison oak or poison ivy.
Other times, it can be harder to know where the rash originated.
There are many possible causes of a stomach rash and many are not cause for concern.
But they all have something in common: If you’ve got a rash on your stomach, you probably want it to be gone!
In this article, I’ll tell you about some of the most common potential causes of a stomach rash.
I’ll talk about their symptoms, including serious symptoms to watch out for, and how these rashes can be treated.
I’ll also tell you when to see a doctor.

Chat NowWhat Causes a Rash on Your Stomach?
Not all stomach rashes are the same.
They may develop quickly, or spread over time. A rash may indicate anything from an allergic reaction to an underlying infection.
There are many possible causes of a stomach rash, which is why it’s important to speak to a provider when you’re unsure about what’s causing your symptoms.
Possible causes of a mild stomach rash include:
- Pregnancy: During the third trimester of pregnancy, an itchy rash can appear in the stretch marks on the stomach. This is called pruritic urticarial papules and plaques of pregnancy, or PUPPP. This rash looks like little pink pimples or hives inside the stretch marks. The rash usually goes away within 1-2 weeks of delivering your baby. A PUPPP rash can be very itchy, but it shouldn’t cause complications for you or your baby.
- Scabies: This pimple-like rash is caused by an infestation of skin mites. The human itch mite, or scabies mite, burrows into your skin and lays eggs. The resulting rash is very itchy, especially at night; the rash may also have scales. Scabies can be spread from one person to another via prolonged, skin-to-skin contact—institutions such as nursing homes and child care facilities are often the sites of scabies outbreaks. Scabies can be cured by a prescription scabicide—a product that kills the mites and their eggs.
- Ringworm: This rash is not caused by a worm, as its name suggests. Ringworm is caused by a fungus, and it usually becomes a red, scaly rash in a circular—or ring-like—pattern. You can get ringworm from contact with another person who has a ringworm infection, or from an animal or object that has the fungus. Athlete’s foot and jock itch are types of ringworm. If you have it on your stomach, it’s possible that jock itch has spread up from your groin area to infect your stomach. Over-the-counter antifungal treatments can help; if they don’t, contact a doctor.
- Scarlet fever: Scarlet fever is caused by the same bacteria that causes strep throat. If your child has a sore throat and a rash, they may have contracted scarlet fever. The rash usually starts on the neck, armpits, or groin, but can spread to other parts of the body, including the stomach. The rash will feel like sandpaper. Scarlet fever is more common in children, but adults can get it, too. If you or your child has scarlet fever, you’ll need antibiotics to clear the infection.
- Contact dermatitis: Contact dermatitis is a type of rash that can happen when your skin comes into contact with irritants, or if you have an allergic reaction to something you’ve touched. Symptoms of contact dermatitis include redness, itching, swelling and stinging of the skin. Other times, you may experience blistering or an oozy rash, like those caused by poison ivy, poison oak, and allergic reactions. Contact dermatitis is not contagious and cannot be spread through the fluid caused by blisters.
- Eczema: Eczema refers to several types of allergic skin conditions. Eczema rashes are often red, dry, and very itchy. They can appear on the face, hands, feet, inside of elbows, behind the knees, or on the stomach. Though experts don’t fully understand the connection, people with eczema are more likely to develop asthma or experience regular allergies. The severity of eczema may change over time, but it’s typically a chronic condition.
- Psoriasis: The stomach is a common area for a psoriasis flare up. Psoriasis is a chronic skin disorder that causes thick pink or red patches on the skin, often covered with white or silvery scales called plaques. Psoriasis is caused by an immune disorder, and is often an inherited condition.
- Impetigo: Impetigo is a highly contagious bacterial skin infection that is more commonly found on infants and young children. The main symptoms of impetigo are reddish sores that ooze. These sores usually form around the nose and mouth, though they can form elsewhere on the body, including the stomach. Antibiotic ointment or cream prescribed by a provider is required to treat the infection.
Possible causes of a more serious stomach rash include:
- Allergies to food or medication: Allergic reactions to medications can happen when a substance that you’re allergic to comes in contact with your skin or enters the body through the mouth. Some allergic skin reactions can be mild, while others may be more life-threatening. If you or a loved one is experiencing a severe allergic reaction, reach out to a provider or seek emergency care immediately.
- Lyme disease: Lyme disease is extremely common in the United States and is transmitted to humans through the bite of infected ticks. Symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans (EM). The appearance of an EM rash can vary widely. It is generally described as target-like. It usually begins as a small bump or redness at the site of the bite and then gradually expands, sometimes reaching up to 12 inches in diameter.
- Kawasaki disease: Kawasaki disease (KD) is an extremely rare but serious disease that primarily affects children five years and younger. As few as 20 children in 100,000 in the United States have this condition. Though the exact cause of KD is unknown, it can cause fever for longer than five days, rash, swelling of the hands and feet, irritation and redness of the whites of the eyes, swollen lymph glands in the neck, and irritation and inflammation of the mouth, lips, and throat. Post-COVID multisystem inflammatory syndrome in children (MIS-C), is a rare condition that occurs about one month after an infection with COVID-19 and can cause similar or identical symptoms. This may be seen in children up to 17 years old.
- Viral infection: Multiple viruses can also produce a rash. Viral rashes often come with additional viral symptoms, such as fever, diarrhea, runny nose, cough, or sore throat. Your healthcare provider can often recognize a viral rash based on its appearance and your other symptoms.
Symptoms of a Stomach Rash
A stomach rash can cause a wide array of symptoms, depending on the type of rash present.
Generally, a rash involves a change in the color, feeling, or texture of your skin.
Some symptoms you may experience with a stomach rash include:
- Dry, red, itchy skin
- Small blisters or bumps
- Thick, pink or red patches on the skin
- White or silvery scales on the skin
- Painful patches of skin
- General itchiness
Serious symptoms
Sometimes, a stomach rash can be a sign of a more serious condition.
In those cases, there may be additional symptoms present, like:
- Fever
- Chills
- Joint pain or stiffness
- Change in consciousness (including unresponsiveness or fainting)
- Purple-colored rash
- Shortness of breath or difficulty breathing
- Sudden swelling of the face, lips, or tongue

If you or a loved one experiences any of the above symptoms, seek emergency care as soon as possible.
What are the Treatments for a Stomach Rash?
The appropriate treatment for a skin rash depends on the cause of your symptoms.
Speak to a provider to determine which treatment option, if any, is right for you.
Prescription medications
Some skin rashes, including psoriasis and eczema, may be treated with prescription lotions, ointments, and/or oral or injectable medications.
Over-the-counter (OTC) medications
In many cases, over-the-counter (OTC) medications like hydrocortisone cream or calamine lotion can help to soothe your rash, no matter the cause.
Other OTC medications, like ibuprofen (Advil) or acetaminophen (Tylenol), may help to alleviate pain associated with your rash. Antihistamines like loratadine (Claritin), cetirizine (Zyrtec), and diphenhydramine (Benadryl) can be helpful in treating rashes and itching.
Home remedies
Before resorting to home remedies, consult with a healthcare professional to determine whether certain home remedies will make your symptoms better or worse.
If your provider says they are safe, home remedies can help soothe the discomfort and pain caused by some skin rashes.
A cool bath with baking soda, uncooked oatmeal, or colloidal oatmeal can help soothe the itching caused with chickenpox, poison ivy, and poison oak.
Stomach Rash Prevention
Not all stomach rashes are preventable.
However, there are some things you can do to prevent certain stomach rashes, including:
- Practice good personal hygiene to help prevent against viral infection, including washing hands thoroughly
- Avoid perfumed soaps and laundry detergents
- Moisturize your skin with a fragrance-free moisturizer, especially in dry and colder temperatures
- Get vaccinated whenever eligible, including the rubella and chickenpox vaccines

If you’ve developed a mild rash and are not experiencing any other symptoms, it’s OK to try some over-the-counter treatments and to wait a few days to see if your rash will go away on its own.
If the rash persists for a few days, spreads, becomes painful or infected, or you develop a fever, your rash may indicate a medical condition that requires treatment.
If you experience severe symptoms, or if signs of a new rash don’t go away on their own within one week, reach out to your provider.

Rash on the abdomen in an adult: what could it be?
Eruptions on the abdomen can be very annoying, especially when accompanied by symptoms such as itching or burning. There can be many reasons for this ailment, we will consider the most common of them.
Types of rashes in adults
Urticaria
Reddening of the skin is accompanied by the appearance of small blisters, slightly elevated above the level of the skin, similar to those that appear after contact with nettles. nine0003
Spotted rash
Spots of indeterminate form appear on the body, usually red. They can merge with each other into small islands or be at a distance from each other. Do not rise above the surface of the skin or rise almost imperceptibly. Such a rash may disappear when the skin is stretched or pressed against it.
Papular rash
Papules are small hard blisters filled with solid contents. They feel like solid masses, look like small, firm pustules that are not filled with fluid. Their diameter can reach from 1-3 mm to 1-3 cm.
Bubble (vesicular) rash
Blisters on the skin can be filled with either clear or purulent fluid (then called pustules), tend to merge with each other [1].
Probable causes of rashes on the abdomen in adults
Skin changes on the abdomen or other parts of the body can occur for many reasons. Among the most common are allergies and some infectious diseases.
Skin diseases
This is a large group of diseases, the main manifestations of which are changes in the skin. They can be acute and chronic, infectious and non-infectious. A dermatologist deals with the treatment of skin diseases.
Skin diseases that can cause a small red rash on the abdomen include: neurodermatitis, Gibert's pink lichen, eczema, polymorphic photodermatosis, psoriasis, acne and others. Each of these pathologies has its own characteristic symptoms and features of skin manifestations [1]. nine0003
Diseases of a viral nature
Chickenpox
Chickenpox causes a rash to appear on the abdomen, back, arms, legs and face. At the beginning of the disease, these are small redness in the form of spots, which eventually transform into larger vesicles that dry out after opening. In adults, chickenpox may leave small scars [2].
Shingles
Another disease caused by the varicella-zoster virus is shingles. Before the appearance of skin changes, patients feel pain, burning and itching along the course of the nerve that was attacked by the virus. The rash is grouped into characteristic stripes along the body along the intercostal spaces. Skin lesions look the same as with chicken pox, that is, they go through stages in the form of spots, vesicles and drying of the vesicles. [3]. nine0003
Measles
The main symptoms of measles are cough, fever, redness and small spots on the face. As the disease progresses, papules may appear all over the body, but they do not require serious treatment, as they disappear on their own after a few days. As a treatment, dry ointments, for example, with zinc oxide, can be used. Remember that measles should always be diagnosed by a doctor, as it can have serious complications [4].
Allergy
We are surrounded by a huge number of allergens, so one of the most common causes of a rash on the stomach is an allergic reaction. It can be caused by chemicals used for washing, the material from which clothes are made, food, pets, cosmetics, and medicines. A rash on the abdomen caused by an allergy usually presents with redness, small spots, hives, itching, or dry, flaky skin.
Allergy treatments include antihistamines and ointments or creams that moisturize and soothe itchy skin. To avoid such a rash in the future, it is recommended to consult an allergist and carry out allergy tests. In people prone to frequent allergic rashes, it is recommended to use hypoallergenic cosmetics, emollients specifically designed for allergic skin, and limit the consumption of highly allergenic products during daily care [5]. nine0003
Rash in diseases of the gastrointestinal tract
Skin manifestations often accompany diseases of the intestines and stomach. Violation of the absorption of vitamins, minerals and nutrients affects the condition of the skin and mucous membranes [6]. Congenital deficiencies usually appear at an early age.
In adults, the rash is associated with atopic reactions of the digestive system - such as irritable bowel syndrome, ulcerative colitis, colon polyposis, Helicobacter pylori infection (gastritis, duodenitis). There is an assumption that Helicobacter pylori can provoke the development of psoriasis [7]. nine0003
A bright rash is one of the important symptoms of typhoid fever [8].
Sexual infections
A small red rash on the abdomen is manifested in the following sexually transmitted diseases:
- second stage of syphilis;
- pubic pediculosis [9].
Rash on the abdomen with scabies
The scabies mite causes an itchy rash on the abdomen, the infection spreads by self-infection during scratching of the scabies in the thickness of the skin. The sooner scabies is diagnosed, the sooner you can get rid of it. It is very important not to scratch the lesions on the skin, and wash clothes and bedding at high temperatures [10]. nine0003
Infectious skin rash
Rash should not be taken as an isolated symptom. Infectious diseases also have the following signs:
- fever, chills, aches, general malaise;
- enlarged regional lymph nodes;
- the presence of an entrance gate of infection;
- history of contact with infected people;
- specific changes in blood tests and biochemical analysis, characteristic of the infectious process (increased ESR, shift of the leukoformula, the appearance of C-reactive protein, etc.). nine0084
Infections with skin manifestations include herpes, typhus, leptospirosis, rubella, hemorrhagic fevers of various origins, infectious mononucleosis, meningococcal infection, measles, typhoid fever, chickenpox, Rosenberg's erythema, paratyphoid fever, Lyme disease, pseudotuberculosis, salmonellosis , scarlet fever, enterovirus infection, Chamer's infectious erythema, erythema nodosum, etc.
Only a doctor can understand this variety. Therefore, if there are signs of an infectious disease, you should not self-medicate [11]. nine0003
Skin changes in Fabry disease
Fabry disease is a congenital disease of a genetic nature, which is accompanied by a variety of clinical manifestations. One of the characteristic symptoms of Fabry disease is angiokeratomas on the abdomen - small dark red (up to purple) rashes. They can also appear on the face, in the anus, on the fingers and toes. The elements of the rash slightly rise above the surface of the skin, inside there is a dense content.
In addition to the rash, patients complain of burning pain in the arms and legs, visual and hearing impairment, and abdominal pain. But, since the rash immediately attracts attention, this is often the first reason to see a doctor. With timely early diagnosis, the progression of Fabry disease can be slowed down with the help of modern enzyme replacement therapy [12].
Diagnosis of rashes on the abdomen
If a rash appears on the abdomen, you should consult a general practitioner or therapist who can make a diagnosis or refer you to a specialist (allergist, dermatologist, gastroenterologist, infectious disease specialist, etc. ). nine0003
After questioning, examination and palpation of the elements of the rash, the doctor may prescribe additional examination methods:
- complete blood count, urine, feces, biochemical blood test;
- dermatoscopy;
- biopsy or scraping of elements of the rash;
- PCR, ELISA and other methods for the detection of specific pathogens;
- endoscopic methods: FEGDS, colonoscopy, etc.; nine0084
- consultations of narrow specialists.
