If you’re interested in living a healthy lifestyle, you’ve probably heard of the ketogenic diet.

The keto diet is an acronym for the ketogenic diet, which is a low-carb, high-fat diet.

When you eat low carbohydrate meals, your body runs on ketones rather than glucose from carbs. This causes your body to burn fat as a source of energy, resulting in weight reduction.

However, we must bear in mind that there may be some negative effects while starting a ketogenic diet, as the body undergoes a significant transformation.

Tiredness, stomach discomfort, dizziness, and even keto rash are some of these side effects.

You’ll learn what the keto rash is, what causes it, and how to avoid and manage it in the sections below.

What is Keto Rash, exactly?

Keto rash is a very uncommon inflammatory condition of uncertain origin; the disease’s specific etiology is unclear.

The rash appears as penetrating, high-level skin lesions. Depending on the stage of the illness, these lesions might be red, brown, or pink.

Keto rash is comparable to eczema or dermatitis and mainly affects the neck, shoulders, back, chest, torso, and axial regions, with the face and extremities of the body being the exception.

If you try to exercise, expose the rash to moisture, heat, or rub it, the keto eruption will worsen, just like any other rash.

Fortunately, this rash is not life-threatening, even though it is uncomfortable.

What Does Keto Rash Feel Like?

According to research involving young Japanese women, keto rash is a kind of dermatitis that may affect anybody, although it is especially common among Asian women.

Rashes may cause the following symptoms:

  • some red dots, known as papules, that resemble spiderwebs;
  • a rash that irritates your skin;
  • mostly affects the upper back, chest, and abdomen

There are some dark marks on the skin after the stains have faded.

What Causes Keto Rash When You’re on a Low-Carb Diet?

Although various investigations on keto rash have been undertaken, the specific cause of this ailment has yet to be established; nonetheless, there are certain linked disorders such as Sjogren’s Syndrome, H. Pylori Infection, and Still’s Disease.

The following are some of the possible reasons of keto rash:

  • Prolonged Fasting Intervals: In one research, half of those who did it had a rash because their blood sugar levels were so low, and ketosis may induce the rash.
  • Acetone secretion might be the major cause of ketones. The quantity of acetone in the body might rise to the point where the body begins to sweat an excessive amount of acetone, irritating the skin and causing the keto eruption.
  • Allergic Reactions — Beginning a low-carb diet requires adding items that you were previously consuming, which might trigger allergic reactions and result in a keto rash. Keep track of the new meals you’ve added since beginning the keto diet to determine if there’s anything new that’s causing it.
  • Nutrient deficit and prurigo pigmentosa may result from eliminating an entire food category and not taking any supplements to get over the keto flu.
  • Candida eradication

Ketosis and prurigo pigmentosa have been linked by some experts, however the specific etiology of the condition has yet to be discovered.

The presence of ketosis, which arises as a consequence of a restricted diet but may also be present in diabetics, is linked to cutaneous rash.

It has been revealed that some persons have developed a rash as a result of dietary modifications.

Other variables, according to some, might worsen this illness, including:

  • sunlight
  • heat exhaustion
  • sweating
  • rubbing on the skin
  • trauma to the skin
  • allergy to certain foods;

What Is the Duration of Carb Withdrawal Rash?

Unfortunately, there is no definite period when the keto rash will go away. It might take a few weeks to months for some individuals, while it could take a few months to a few years for others.

The eruption usually subsides after one or two weeks. Only a few individuals have the misfortune of having to deal with this disease for an extended length of time.

It’s important to remember that if the source and trigger factors are addressed, the rash will go away.

How to Get Rid of Keto Rash

There are a few options for treating keto rash:

  1. Reintroduce carbohydrates into your diet – If you suspect your skin rash is caused by a recent diet change, it’s a good idea to start eating more carbohydrates. The return of carbs into the diet, according to a 2008 research, dramatically alleviated the symptoms of the rash. If you don’t want to completely abandon the keto lifestyle, you may stick to a low-carbohydrate diet.
  2. Nutritional deficiencies, particularly vitamin A, vitamin B-12, and vitamin C, may play a significant role in skin inflammation. A limited diet does not provide your body with all of the vitamins and minerals it requires. As a result, you must consume a variety of colored fruits and vegetables in order to get all of the nutrients your body requires.
  3. Supplement your diet with anti-inflammatory supplements – It’s a good idea to take supplements that aid your body battle inflammatory affections when you modify your diet. Probiotics, prebiotics, fish oil supplements, and vitamin D, which helps reduce dermatitis symptoms, are some of these.

The National Eczema Association suggests cleaning your skin with lukewarm water in the shower or bath, and only using gentle and specific skin soaps and oils.
  5. Eliminates food allergies – Because the keto diet is low in carbohydrates and high in fat, it includes items like milk, eggs, fish, nuts, and seeds. Unfortunately, these items are on the list of common food allergies. Food allergens cause inflammation, thus they should be avoided in your diet to avoid exacerbating the rash’s symptoms.
  6. Request suitable medicine from your doctor – We highly advise you to see your doctor to establish what caused this response and to get the proper therapy. Doxycycline and Minocycline antibiotics are the best treatments for this illness, while Dapsone (which has more adverse effects than the other two) is also utilized.

Reduce carbohydrate intake gradually — A complete removal of carbs and a conversion to a high-fat diet may have a number of negative consequences on the body, therefore it’s best to do so gradually. You may also take a multivitamin every day to avoid nutritional deficit while starting the keto diet.
