| cardiac insufficiency | A condition where there is ineffective pumping of the heart leading to an accumulation of fluid in the lungs.

| valvular insufficiency | A leaky state of one or more of the cardiac valves, the valve not closing tightly and blood therefore regurgitating through it. Synonym: valvular incompetence, valvular insufficiency. (05 Mar 2000) |
| pancreatic insufficiency | Not enough of the digestive enzymes normally secreted by the pancreas into the intestine. Pancreatic insufficiency is a hallmark of cystic fibrosis. (12 Dec 1998) |
| velopharyngeal insufficiency | Failure of the soft palate to reach the posterior pharyngeal wall. It may be caused by cleft palate surgery, palatal or pharyngeal abnormalities or injury, or neuromuscular dysfunction of the velopharyngeal sphincter. It causes hypernasality of speech. (12 Dec 1998) |
| venous insufficiency | <cardiology, surgery> A condition in which the vein do not channel the flow of blood adequately. most often this condition is seen in the veins of the lower extremities. Symptoms include leg swelling, leg pain and muscle cramps. This condition can predispose to venous thrombosis. (12 Jan 1998) |
| parathyroid insufficiency | <endocrinology> A term which describes the abnormally low production of parathyroid hormone by the parathyroid glands.

| renal insufficiency | Defective function of the kidneys, with accumulation of waste products (particularly nitrogenous) in the blood. (05 Mar 2000) |
| respiratory insufficiency | Failure to adequately provide oxygen to cells of the body and to remove excess carbon dioxide from them. (12 Dec 1998) |
| chronic adrenocortical insufficiency | Adrenocortical insufficiency usually as the result of idiopathic atrophy or destruction of both adrenal glands by tuberculosis, an autoimmune process, or other diseases; characterised by fatigue, decreased blood pressure, weight loss, increased melanin pigmentation of the skin and mucous membranes, anorexia, and nausea or vomiting; without appropriate replacement therapy, it can progress to acute adrenocortical insufficiency. Synonym: Addison's disease, addisonian syndrome, hyposupradrenalism, morbus Addisonii. (05 Mar 2000) |
| chronic venous insufficiency | <cardiology> A condition in which the vein do not channel the flow of blood adequately. most often this condition is seen in the veins of the lower extremities. Symptoms include leg swelling, leg pain and muscle cramps. This condition can predispose to venous thrombosis. (27 Sep 1997) |
| mitral insufficiency | Malfunction of the mitral valve. Mitral insufficiency allows the backflow of blood (regurgitation) from the left ventricle into the left atrium. (12 Dec 1998) |
| mitral valve insufficiency | Backflow of blood from the left ventricle into the left atrium, owing to imperfect functioning of the mitral valve. (12 Dec 1998) |
