Everybody farts. However, not everyone knows what a fart is, or what they mean for health. Here is the final installment of a three part series on farts.

Farts can be embarrassing, especially smelly ones. But in rare cases, it can be more serious than that. In addition to regularly bad smelling farts, see a doctor if you experience weight loss, pain, vomiting, or any other strange symptoms.

Any of these, in addition to foul farts, could mean  carbohydrate malabsorption, lactose intolerance, and infection.

Carbohydrate malabsorption ranges from mild to incredibly severe. Many know this as a gluten intolerance, and at its most serious, Celiac disease. Mild carbohydrate malabsorption is accompanied by abdominal pain and often bloating. To avoid smelly farts due to carbohydrate malabsorption, cut out gluten from your diet, which is found in breads and grains.

Lactose intolerance is fairly common, and is found in dairy products. Lactose requires a lot of enzymes to break down, and when we have no enzymes to break them down, the lactose sits in our digestive tract. Odor causing bacteria feeds on this stationary lactose and produces a bad odor. Again, avoid dairy for less flatulence.

Digestive tract infections are usually obtained through travel to foreign places. Likely with a digestive tract infection, diarrhea, fever, and abdominal pain will follow. Consult a doctor if you suspect that you have a digestive tract infection.

Fart on, friends!
