Here we have discussed all about keto rash and also about the treatment of keto rash.  A ketogenic diet may be the only thing that causes keto rash, which is sometimes referred to as prurigo pigmentosa and is an uncommon inflammatory skin disorder or skin dermatitis. The rash appears as itchy, raised sores on the skin that can be any colour (pink, red, and brown). While annoying, it poses no threat. Fasting, diabetes, and the Keto diet can cause ketosis and subsequent keto rash, but if you don’t stop exercising or protect your skin from heat, friction, and moisture, the rash may get worse. After the worst-case scenario, the body goes into ketosis and causes a keto rash; otherwise, it goes away in a few weeks.  Read more


There are four main stages to keto rash, which are as follows.

initial lesions The skin condition known as “urticarial populoplaques” had pale pink lesions that resembled scratch marks. This stage is transient and can be dismissed as a passing rash.
Papules, which are completely developed lesions on the skin, are red in colour, and this causes individuals to worry about a full-blown rash.
Lesions are getting darker and rashes are beginning to heal at this stage. In this scenario, scaly papules can occasionally be detected.
Although late lesions in this stage are healed, the mark known as “reticulated hyperpigmentation” still exists. Larger than freckles are the darker areas that remain after the lesion.

Keto Rash Indicators

Both pregnancy and menstruation are times when hormone shifts might happen.

  • Allergens

Ketogenic diets made the body react to them in an allergic way.

  • nutrient shortage

If a person follows a diet that is extremely low in carbohydrates, nutrient shortage may happen and result in a rash.

  • Ketone molecules

The acetone the body produces while in ketosis causes perivascular inflammation, which can result in swelling around the blood vessels and cause rash.

  • extreme fasting

Ketosis brought on by low blood sugar levels might result in a rash.

Treatment and cure of Keto Rash

Give it time to heal on its own keto rash can be brushed off on its own in a couple of weeks sometimes treatment is also not needed because it is recovered by the defense mechanism of the body but if the rash doesn’t go on its own you should look for some other options.

  • Rule out allergies

Try to eliminate some keto-friendly food (fish, shellfish, eggs, dairy, and nuts.) from your diet to check the real cause of allergy.  Eliminate this diet for 30 days and look for the symptoms if your health improves try to add one keto-friendly food to your diet and in addition if no symptoms appear to try to add another keto-friendly food the rash appeared after the addition of any food that food triggers allergies and rash in your body. Try to avoid that food and continue your diet.

  •  Eat carbohydrate-rich foods

Carbohydrate deficiency can cause ketosis that can lead to keto rash. Try to eat foods rich in carbohydrates to get rid of ketosis and look for rash if it doesn’t appear to lower the consumption of carbohydrates again if there is ketosis then your body is sensitive to ketone bodies. In this situation, you should consume 50-100 g of carbohydrates in a day.

  • Insulin

People with diabetes can reduce the risk of ketosis and keto rash by just administrating insulin.

  • Supplements

vitamin D and vitamin A can regulate inflammation hence keto rash is an inflammatory disease so consumption of these vitamins can help.

Calcium, sodium, potassium, magnesium are necessary for the energy and functioning of cells these minerals diminish during a change in the ketogenic diet.

Bile salts cholic, deoxycholic, and lithocholic acid helps your body to convert fat into fatty acids.


Consult your doctor to use medication for the keto rash. Some antibiotics show good results in healing keto rash

  • Doxycycline
  • Minocycline
  • Dapsone

Dapsone replaced minocycline because of lower side effects and gives longer remission.

To prevent the cause of the keto rash, alter your lifestyle and avoid a number of foods;

Because sweat is a significant rash trigger, avoid sweating. Avoid going to the gym or limit your time doing strenuous exercise to avoid sweating.

  1. Avoid rubbing because it can severely exacerbate the rash.
  2. Try to avoid rubbing or wear loose-fitting clothing.
  3. On the skin, stay away from exfoliants like DIY scrubs.
  4. After a bath, try not to scrape too vigorously.
  5. Apply bandages and refrain from scratching.
  6. Attempt to relax.



Since the precise cause is still unknown, there aren’t many ways to stop keto rash. Here are some preventative measures you can take.

  1. Don’t drastically reduce your carbohydrate intake.
  2. To prevent a keto rash, pay attention to rash symptoms and up your carbohydrate intake.
  3. Every time you follow a ketogenic diet, start taking supplements to make up for any deficiencies.
