Functional Dyspepsia

Functional Dyspepsia (FD) or as it was previously known, Non-Ulcerative Dyspepsia is a medical condition that is characterized by recurrent or chronic pain in the upper abdomen, feeling fuller than expected when eating and can also be accompanied by nausea, bloating, belching and heartburn.

Although FD is a medical condition, it is a condition without any evidence of organic disease. It is common in about 15% of the population in western countries.

FD is suggested to be caused by gastritis and medications including nitrates (for angina), corticosteroids, non-steroidal anti-inflammatory medication, and calcium antagonists (for angina or high blood pressure) to name a few. If you have any questions regarding the effects the medication you may be taking is having on your gut, please consult with your G.P or medical specialist.


Gastroparesis is a medical condition involving delayed gastric emptying or paresis (partial paralysis) of the stomach. This results in food remaining in the stomach for longer than is normal.

These are number of possible causes of gastroparesis, some of these including damage to the vagus nerve, effects of certain cancer treatments or other drugs that affect digestive action. Gastroparesis may also result from abnormal eating patterns like anorexia nervosa or bulimia.
Idiopathic gastroparesis ( IG, gastroparesis with unknown cause) may be due to autoimmune response triggered from an acute viral infection. IG accounts for a third of all chronic cases)
