Does heart failure cause nausea and vomiting?

Nausea and/or abdominal swelling in CHF may be the result from the buildup of fluid in the body and the backup of blood in the liver. There is a strong connection to nausea and the liver, even in healthy individuals.

There is known digestive dysfunction with CHF. The pancreas is part of the digestive system. The pancreas is responsible for the amount of insulin secretion.

It is also known and common for heart failure to cause hypoglycemia. Hypoglycemia occurs when the pancreas secretes too much insulin and too much glucose is taken out of the bloodstream resulting in what is known as a "blood sugar drop". This drop can cause nausea. If the blood sugar is the issue in an individual with CHF, they can try eating some fruit or drinking some Orange Juice to reduce the nausea feeling.
