Often we find complaints that people tend to get headaches during their fasting days. The question is Why Does Fasting Cause Headaches ? Let us at the foremost understand that not all people get headaches during their fasting days. It solely depends upon person to person and their physical condition. In this article we will try to find an answer to this very pertinent question.

In strict medical terminology and its analysis, headaches during fasting may be caused due to hypoglycaemia. Hypoglycaemia is a medical condition in which the blood glucose level in our body drops below normal. In other words we can safely say that low blood sugar which may be the result of fasting may cause headaches some times. In this instance, we must remember that headaches during fasting may not be necessarily caused due to hypoglycaemia alone. There are many other factors which may cause headaches during fasting. In the following paras we are going to enumerate most of them one by one.

Hypogycaemia

As discussed above, while dealing with the question of Why Does Fasting Cause Headaches, We come across the term Hypoglycaemia. Hypoglycaemia is a clinical syndrome of the body in which glucose level in our blood drops below the normal level. There are many causes of such drops and fasting is one such cause. One may remember here that fasting for short duration does not cause hypoglycaemia. Often Hypoglycaemia is caused due to prolonged fasting.

Stress Hormones

During fasting, stress hormones are released from our bodies which often triggers anxiety and resultant lack of sleep and ultimately leading to headaches which may be lightheadness or moderate to severe headaches.

Dehydration

Why Does Fasting Cause Headaches ? Fasting leads to dehydration in our body and which in turn causes headaches.

Dr Ebrahim Elimam, a known consultant for diabetes, endocrinology and internal medicine at Health Plus Diabetes and Endocrinology Center, Riyadh explain the phenomenon as follows:-

When the brain detects that the water supply is too low, it produces histamines (compounds released by cells that cause contraction of smooth muscle and dilation of capillaries) to ration and conserve water in case the water shortage continues for a long time. These histamines directly cause pain and fatigue, which is experienced as a headache and lowered levels of energy.

Depletion of Electrolytes

For the efficient performance of our brain and the nervous system, sodium and potassium level in our blood stream should be adequate and always at the normal levels. Lowering of sodium or potassium in the body may cause low blood pressure and some time even discomforts caused at the hemisphere of the brain mainly due to lessened potassium levels. These symptomatic conditions are often caused due to prolonged fasting hours which ultimately causes headaches. Hope you found an answer to the pertinent question Why Does Fasting Cause Headaches ?

Withdrawal Syndrome

Often we are practiced to drink a lot of tea or coffee during the day hours and during fasting times we have to forsake these habits. Withdrawal syndrome caused due to non drinking or tea or coffee or in other words absence of caffeine which our body has become accustomed to may lead to headaches

It must be remembered that often headaches as a syndrome during fasting days occur at the initial few days only and later on when the body is more accustomed to it and it learns to stay put by burning the body fat, than headaches often does not occur.

To cope up headaches during fasting days, one may consume enough fluids, green vegetables, fruits and fruit juices which helps to reduce the effect of many of the above discussed factors and thus may help to avoid headaches during the fasting days.
