How does too much orange juice affect the body?

Drinking too much orange juice can adversely affect the body. Orange juice contains natural fructose, or sugar. Drinking several glasses of orange juice daily may lead to weight gain due to the increased number of calories in the diet.

Orange juice also contains citric acid, which affects people who suffer from heartburn, or acid reflux. It can cause severe stomach pain and vomiting in sensitive individuals.

Too much orange juice may also lead to gout in susceptible individuals. Gout is caused by a build up of uric acid in the joints. Due to its high fructose content, orange juice is one of the foods and beverages that may lead to excess uric acid in the body.
