Heart palpitations after eating is usually normal as it indicates the digestion process has started, and therefore a lot of blood is being pumped to aid in the body function.

The digestion process is complicated as the body has to break down the food consumed, and they are finally absorbed into the system. It is a process that requires the stomach to work hard, and therefore more blood supply is needed in that area.

Let’s look into the details about what heart palpitations after eating mean and their causes, symptoms, and treatment.

What are heart palpitations after eating?

The condition of heart palpitations after eating is when a person feels that his heart is ‘racing’ after a meal. This may be felt immediately after a meal or may start while the person is still eating.

Heart palpitations after eating are a common complaint in overweight people and sometimes in recovering anorexic patients.

Heart palpitations after eating are normal after having a meal because the heart needs to pump more blood to the stomach and adjoining areas. Thus, it needs to bring about an increase in the blood supply to the stomach to assist the process of digestion.

This is important since increased blood flow in the abdominal region immediately after a meal helps digestion and assimilation of food. Hence, for some people, this routine activity of the heart could manifest as heart palpitations.

One can follow specific guidelines to help prevent heart palpitations after eating and keep the heart health in good condition.

Regular meals in small portions help energize the body on a timely basis and thus, prevent any sudden spurt of hormonal activity that may cause irregularities in the functioning of the heart.

Moreover, one can get a regular check-up to look out for hormone levels and check on the body’s iron levels. Also, reduce sugar and coffee and use breathing techniques to reduce stress.

If the heart palpitations after eating symptoms worsen with time, it is best to get a full cardiac scan done using a Holter monitor.

Thus, to keep the heart palpitations after eating at bay, ensure that you follow a healthy lifestyle, with a good and nutritious diet supplemented by regular exercise.

Foods that can cause heart palpitations

There are many different foods that you can eat that may cause heart palpitations.
