What is FD?
FD (persistent or recurring indigestion with no known organic cause) is a relatively common and often frustrating condition. It is a disorder of sensation and movement in the organs of the upper digestive tract where the normal downward pumping and squeezing is altered, and the digestion and absorption of food nutrients is affected. Functional Dyspepsia often reoccurs over time.

What Causes FD?
Most doctors are not sure what causes FD. In the absence of a known organic cause, it is thought that the function of the stomach and the first part of the small intestine (the duodenum) may be altered in some way, which can disturb the movement, digestion and absorption of food.

What are the Symptoms of FD?
In addition to impacting the digestion and absorption of food nutrients, the main symptoms of FD are in the upper belly and include:
• Pain and discomfort
• Early fullness with meals
• Nausea
• Bloating
• Belching

Where do the Symptoms of FD Occur in the Digestive System?
FD occurs in the upper belly above the naval. In FD, the stomach does not expand normally in response to a meal, which means the food eaten backs up in the stomach and the upper part of the small intestine.
