Thorough examination of this cough will require a skilled lung specialist, called a pulmonologist. This will include a number of tests such as, examining tissue from the lymph
nodesLymph node biopsy
Swollen glands
Swollen lymph nodes in the groin
Swollen lymph nodes under arm through a microscope, a CT scan of the chest, and probably a
bronchoscopyBronchoscopy
Bronchoscopy with transbronchial biopsy. When the problem is not seen on a CT scan, then a
bronchoscopyBronchoscopy
Bronchoscopy with transbronchial biopsy is done. During this procedure a bronchoscope is passed through the
noseNose fracture into the windpipe to look inside the lungs. A bronchoscope is a flexible tube with a small camera at one end. With the bronchoscope tiny pieces of lung tissue can be taken for further testing. This is called lung biopsy. It is done to be certain about the cause of the problem.
A thorough examine of the liver by a GI specialist, called a gastroenterologist may also be needed. This examine may include a liver biopsy. This procedure is used to get tissue from the liver to be examined through a microscope. Like the lung biopsy this is done to be certain about the cause of the problem. Your friend should have these examinations without further delay.
The 30-pound weight loss could be a reflection of a loss of appetite due to the severe cough. However it is more likely related to the problem that has caused both the lack of energy and the cough. That problem must be found before proper treatment can be started.
