How intermittent fasting can trigger acidity and gas-related headaches, and what to do about it

So, what are they?

Raj explains that the entire chemical process has its own kind of effects such as hormonal changes, fat oxidation, and gut microbiota modifications. “The ultimate goal behind intermittent fasting is that weight loss is achieved along with some improved cognitive function. However, this kind of diet has some negative effects, like headaches, especially those classified as gas or bloating with headache, which might occur in some individuals,” says the nutritionist.

Raj shares several factors that could contribute to acidity and headaches during fasting:

1. Changes in eating patterns may lead to an individual eating a huge meal or consuming a variety of meals during the eating period. This sudden change could overload the gastrointestinal tract and potentially lead to bloating and discomfort.

2. The nutritionist points out that dehydration may be another reason during fasting periods, since some people may not be drinking enough fluids. Headaches might arise due to lack of hydration.

3. Prolonged fasting may cause an individual to starve for an extended period of time, resulting in fluctuations in blood sugar levels and, ultimately, a headache.

How do you reduce gastric headaches?

Edwina Raj shares various techniques to reduce the chances of fasting-induced headaches:

1. Keep well-hydrated during fasting periods and drink plenty of water.

2. Emphasize the consumption of digestible foods in the eating windows to make digestion easier.

3. Avoid sudden changes to an intermittent fasting routine, as the body needs time to adjust.

4. Monitor food choices to reduce the risk of gas-related headaches in between fasts.
