Many people think that a yellow or green nasal discharge means a bacterial infection, which requires antibiotics but it is not true. It can be a sign that your body is being attacked by either a bacteria or a virus. That said, a yellow discharge does not necessarily indicate a sinus infection.
After the stool is placed in the culture, it may take two to three days for any bacteria that is in the stool to grow. These bacteria can then be isolated and examined under a microscope so that they may be identified. The stool may also be tested for parasites or eggs.
How long does it take to digest food â from the time you eat it to the time you excrete it? Answers from Michael F. Picco, M.D. Digestion time varies between individuals and between men and women. After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. In the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people.
