One of the most common problem in young men is that of Gout. Some prominent causes are:
1. Alcohol (especially beer)
2. Meat, Sea-food
3. Complex Proteins
4. Low water intake
All of the above reasons cause increase in uric acid in the body. Usually the uric acid is usually passed through urine (by kidneys). But sometimes excess uric acid is left in body and it causes formation of urate crystals. These crystals get deposited in the joint area (most commonly under the food of largest toe) and cause sharp pain, redness, swelling (inflammation).
It is thus very important to maintain lower levels of uric acid in the body.
