Lack of appatite, bloating, gas, stomach always gurgling, nausea, pains on the left side by ovaries and discomfort in stomach? what could be wrong?

Intestinal problems : You might have a primary intestinal problem, a gynecological problem, an infection, a medication problem or a psychological problem. Many health problems can present with stomach and digestive symptoms. Check a pregnancy test (unlikely if this has been going on awhile). You should see a doctor for evaluation. I would start with a gynecological or GI evaluation. Your family doc can start this, too.

A lot: Too many possible scenarios to give a good answer here without a MD exam.
