Indigestion is a feeling of discomfort or pain within the lower chest or abdomen caused by gastric acid irritation within the upper part of the gut namely the oesophagus, stomach or duodenum.  For other causes of abdominal pain  see - "indigestion" but the usual types of indigestion are:-

 

Heart burn. A burning feeling in the centre of the chest, sometimes combined with an acid taste in the back of the mouth. Usually made worse by eating a large meal, straining or leaning forward. This is caused by acid from the stomach refluxing back into the gullet.  

Classic indigestion comes on shortly after food and is a described as an intermittent burning discomfort in the top of the abdomen. Often helped temporarily by antacid medication (white medicine).   Caused by irritation of the stomach wall (gastritis or an ulcer).  If discomfort starts on an empty stomach (or starts in the middle of the night) it is more likely because of an ulcer or irritation of the section of gut which immediately follows the stomach called the duodenum. 

Indigestion and more often heart burn are common complaints experienced during chemotherapy or after surgery. The cause of pain is stomach acid, the acid that helps to digest your food. Stomach acid flows up Normally when you eat, food travels from your mouth down the esophagus through the lower esophageal sphincter. If thereís too much acid, or if the sphincter doesnít work properly, food and stomach acid can flow up or reflux into the oesophagus. Acid reflux irritates the lining of the oesophagus causing ulceration and often causes heartburn. If left long enough this can lead to bleeding or stricture formation (causing food to stick in the throat). The steroids or anti-inflammatory drugs often given during chemotherapy can also aggravate indigestion. If marked then further investigation is required and treatments with anti-acids or other drugs.

Drug therapy

antianticids

Zantac (ranitidine) decreases the production of acid from the lining of the stomach.  This protects the stomach, oesophagus and duodenum from irritation and ulceration. It works by blocking a receptor in the stomach call the H2 receptor of the gastric parietal cell - so called H2 antagonist. A tablet containing 150mg of ranitidine twice a day (morning and evening). It doesn't matter exactly what times of day you take it but many people try to take it at the same times each day so its easier to remember. If you forget to take your tablet donít panic but  try not to miss more than one or two tablets in a row. Zantac is generally very well tolerated. Side effects are rare but include headache and  skin rashes Very rarely breast tenderness in men may occur.

Zoton (Lansoprazole), Protium (pantoprazole) or Losec (omeprazole) are very successful in treating the symptoms caused by acid irritation. Even if you don't already have indigestion it is useful to give Zoton to prevent these symptoms developing when steroids are given with chemotherapy. It  decreases the production of acid from the lining of the stomach.  This protects the stomach, oesophagus and duodenum from irritation and ulceration. They work by blocking an enzyme (hydrogen-potassium adenosine tri-phosphatase) of the gastric parietal cell - so called proton pump inhibitor. Side effects are rare but include headache, diarrhoea and  skin rashes. Your doctor should be aware if you have problems with your liver and the recommended dose should not be exceeded..
