Fasting in Ramadan is considered an important act of worship, imposed by the Almighty God on Muslims. It is considered the season to conduct periodic maintenance of the bodies organs. Gastric ulcer patients who decide to fast are advised to ensure they drink large amounts of fluids during Iftar and Suhoor. They are also advised to avoid foods that cause the formation of salt stones that are deposited in the urine as a result of eating a large quantity of milk, cheese, spinach, and cabbage.
Prolonged exposure to the sun and heavy work during the daylight hours should also be avoided for kidney patients who are receiving dialysis. Those who have been cleared to fast by their doctor are advised not to consume too much potassium. Eating and drinking excessive amounts of fat or spices should also be avoided as it can cause indigestion, abdominal pain, excessive gas, and nausea.
Fasting can be a useful practice for those with indigestion, provided they do not have severe stomach ulcers or inflammation of the esophagus. Patients with these conditions are advised to continue taking their medication regularly.
