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.

What 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
Tightness in the throat
Symptoms that do not improve despite treatment

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

When to See a Doctor

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.

A rash is defined as a widespread eruption of skin lesions. It is a very broad medical term. Rashes can vary in appearance greatly, and there are many potential causes. Because of the variety, there is also a wide range of treatments.

A rash can be local to just one small part of the body, or it can cover a large area.

Rashes come in many forms, and common causes include contact dermatitis, bodily infections, and allergic reactions to taking medication. They can be dry, moist, bumpy, smooth, cracked, or blistered; they can be painful, itch, and even change color.

Rashes affect millions of people across the world; some rashes may need no treatment and will clear up on their own, some can be treated at home; others might be a sign of something more serious.

There are a number of potential causes of rashes, including allergies, diseases, reactions, and medications. They can also be caused by bacterial, fungal, viral, or parasitic infections.

Contact dermatitis

One of the most common causes of rashes – contact dermatitis – occurs when the skin has a reaction to something that it has touched. The skin may become red and inflamed, and the rash tends to be weepy and oozy. Common causes include:

dyes in clothes
beauty products
poisonous plants, such as poison ivy and sumac
chemicals, such as latex or rubber

Medications

Certain medications can cause rashes in some people; this may be a side effect or an allergic reaction. Also, some medications, including some antibiotics, cause photosensitivity – they make the individual more susceptible to sunlight. The photosensitivity reaction looks similar to sunburn.

Infections

Infections by bacteria, viruses, or fungi can also cause a rash. These rashes will vary depending on the type of infection. For instance, candidiasis, a common fungal infection, causes an itchy rash that generally appears in skin folds.

It is important to see a doctor if an infection is suspected.

Autoimmune conditions

An autoimmune condition occurs when an individual’s immune system begins to attack healthy tissue. There are many autoimmune diseases, some of which can produce rashes.For instance, lupus is a condition that affects a number of body systems, including the skin. It produces a butterfly-shaped rash on the face.

Rashes come in many forms and develop for many reasons.

However, there are some basic measures that can speed up recovery and ease some of the discomfort:

Use mild soap – not scented. These soaps are sometimes advertised for sensative skin, or for baby skin.
Avoid washing with hot water – opt for warm.
Try to allow the rash to breathe. Do not cover with a Band-Aid or bandage.
Do not rub the rash dry, pat it.
If the rash is dry, for instance, in eczema, use unscented moisturizers.
Do not use any cosmetics or lotions that may be causing the rash – for instance, newly purchased items.
Avoid scratching to lessen the risk of infection.
Cortisone creams that can be purchased over-the-counter or online may ease itching.
Calamine can relieve some rashes, e.g. poison ivy, chickenpox, and poison oak.

If the rash causes mild pain, acetaminophen or ibuprofen may be useful, but these are not a long-term solution – they will not treat the cause of the rash.

It is important to speak with a doctor before taking any medication. Compare brands before purchasing over-the-counter or online products, to ensure the product is suitable.

If a rash occurs with the following symptoms, it is important to visit a doctor:

a sore throat
pain in joints
if you have had a recent animal or insect bite
red streaks near the rash
tender regions near the rash
a large collection of pus

Although the majority of rashes are not a major cause for concern, anyone experiencing the following symptoms should go to the hospital straight away:

quickly changing coloration on the skin
difficulty breathing or feeling like the throat is closing up
increasing pain or severe pain
high fever
confusion
dizziness
swelling of the face or extremities
severe pain in the neck or head
repeated vomiting or diarrhea

which can be very different. However, acne, scratching, and even more sores with crusts will never go away on their own, but can cause serious complications. Therefore, the dog needs professional treatment, which can only be prescribed by an experienced veterinarian. Contacting a specialist when a disease is detected at an early stage will save the pet from suffering.

Causes of a rash on the abdomen of a dog

Such signs are not always a symptom of a serious illness, but may indicate the presence of disorders in the body.

Most often, rashes and other skin defects appear in the following cases:

Allergy. Unfortunately, animals are also subject to this "scourge" of the XXI century. Rashes can be provoked by both external factors (aerosols, household chemicals, unsuitable detergent for washing a dog, and others), and internal factors (nutrition, medication, accidentally eaten plant). With an allergic reaction, the dog suffers not only from rashes, but also from severe itching. Often it is the abdomen and groin that are affected, especially in puppies, because the skin here is the thinnest, most delicate and sensitive.
Ectoparasites (fleas, lice, withers, simple and scabies mites). All these creatures settle on the skin or under it, bite the animal or gnaw through painful passages. They cause severe itching and pain. The dog actively combs the skin, especially on the stomach, where it is very delicate.
Intertrigo. As strange as it may sound, some breeds of dogs suffer from them in the same way as small children. In dogs, this is caused by sweating or moisture ingress, dirt into extensive skin folds, so the rash is more typical for breeds such as pugs, sharpei, mastiffs, bulldogs. Pimples can be located in any fold, but they spread especially strongly on the abdomen and in the genital area, anus. The condition intensifies at elevated air temperature and with excess weight of the animal, with insufficiently good care for it.
Skin diseases - dermatitis, eczema and others. They can be caused by external stimuli or internal pathologies, including nervous shocks. Sometimes sensitive dogs react with rashes to a change in diet, a move, participation in exhibitions, and even the arrival of a new family member, whether it be a child, puppy or other pet.
Bacterial infections. They are often secondary, joining the underlying disease. If the dog has scratched too vigorously or otherwise damaged the skin on the abdomen, infection can lead to suppuration, inflammation, and the formation of painful rough crusts. Increased itching and pain leads to further scratching, which further spreads the infection and aggravates the disease.
Fungus. Ringworm and other types of fungal infections sometimes affect dogs. More often young animals with fragile immunity suffer, as well as old and chronically ill dogs. Fungi are dangerous to humans and spread easily, especially if the animal is in active contact with brethren or other pets and family members. Lichen can "settle" on any part of the dog's body, damaging not only the skin, but also causing patchy or total alopecia. A similar condition can leave round, pinkish, scaly patches on the body, visible on the belly, where the coat is light, short, and sparse in most puppies.

Poor hygiene or, on the contrary, a maniacal desire for cleanliness of a pet can lead to a deterioration in the condition of the coat, drying out of the skin, the appearance of peeling and cracks. If measures are not taken in time, the condition may worsen due to a secondary infection of a bacterial or fungal nature.

Do not wash your dog with preparations intended for humans, let alone use household chemicals, “coarse” alkaline soap. Leaving an animal in the hope that it will clean itself is reckless, especially if the dog lives in the yard or in inappropriate conditions. But washing more often than once a month is not beneficial, as it removes the lipid layer, leaving the dog's skin and coat defenseless against external influences.

Diagnosis

It is impossible to determine the nature of the disease by the appearance of the rash, therefore, in order to receive the correct full-fledged treatment, a diagnosis by a veterinarian is necessary. He will conduct an examination, take samples that will indicate the causative agent of the disease. The prescribed treatment will be specialized and comprehensive, which means it will help to quickly cope with the problem and avoid the development of complications.

Methods of treatment

First of all, it is necessary to eliminate the cause of the disease. If it is an allergy, then you need to eliminate the allergen - inappropriate food, medicine, chemical, and so on. In the presence of parasites, you need to remove them, and then treat the rash, otherwise there will be no positive result.

If the dog suffers from dirt or diaper rash, then it must be washed with a special medicated shampoo, and the wounds should be treated with a drying disinfectant. With proper care, these symptoms disappear quickly.

It is much more difficult to cope with skin diseases caused by internal problems in the body. Hormonal and endocrine pathologies, improper digestion, and disorders of the nervous system can provoke rashes on the abdomen.
