Jahangir Sarwar discovered a few years ago that patients with severe ulcers who fast without taking efficient medicine face consequences such as hemorrhage, pyloric blockage, and ulcer perforation. However, healthy individuals who follow a fasting regimen experience no problems with their digestion because their bodies produce enzymes to break down food into absorbable substances. Fasting can be beneficial for people who have ulcers because it reduces the acidity of the stomach environment. This allows the body to heal itself more effectively. Fasting also forces the body to rely on its digestive system instead of medications which may cause other problems if used long-term. People who are considering following a fasting regimen should know that it is not recommended for those who are eating normally. There are cases where someone with an existing illness may want to try fasting to see if they can cure themselves through lack of nutrition but most health professionals would not approve. Fast only if you are sick or have injured organs that need recovery time. A medical professional should monitor anyone who decides to fast in order to make sure they do not put themselves at risk of other problems.
