An insulinoma is a small tumor in the pancreas that produces an excess amount of insulin. In most cases, the tumor isn?t cancerous. Most insulinomas are less than 2 centimeters in diameter.
The pancreas is an endocrine organ located behind your stomach. One of its functions is to produce hormones that control the level of sugar in your bloodstream, such as insulin. Normally, the pancreas stops creating insulin when your blood sugar drops too low. This allows your blood sugar levels to return to normal. When an insulinoma forms in your pancreas, however, it will continue to produce insulin, even when your blood sugar is too low. This can lead to severe hypoglycemia, or low blood sugar. Hypoglycemia is a dangerous condition that can cause blurred vision, lightheadedness, and unconsciousness. It can also be life-threatening.
An insulinoma usually needs to be surgically removed. Once the tumor is removed, complete recovery is very likely. An insulinoma is a rare tumor of the pancreas. It?s made of calls called beta islet cells, the same ones in the pancreas the make insulin and control your blood sugar. Normally, your pancreas makes more insulin when your blood sugar is high and less when your blood sugar is low. But an insulinoma constantly makes insulin, even when your blood sugar gets too low.
You might hear an insulinoma called a "neuroendocrine tumor" because it starts in special cells in your body called neuroendocrine cells. These tumors are usually small (less than an inch), and almost all of them are not cancer. In most cases, surgery can cure them.
Typhoid fever is a systemic infection caused by Salmonella Typhi, usually through ingestion of contaminated food or water. The acute illness is characterized by prolonged fever, headache, nausea, loss of appetite, and constipation or sometimes diarrhoea. Symptoms are often non-specific and clinically non-distinguishable from other febrile illnesses. However, clinical severity varies and severe cases may lead to serious complications or even death. It occurs predominantly in association with poor sanitation and lack of clean drinking water. According to the most recent estimates, between 11 and 21 million cases and 128 000 to 161 000 typhoid-related deaths occur annually worldwide. A similar but often less severe disease, paratyphoid fever, is caused by Salmonella Paratyphi A and B (or uncommonly Paratyphi C).
