Lactose intolerance symptoms
Lactose intolerance symptoms often begin about 30 minutes to 2 hours after eating or drinking milk, dairy products, or other food containing lactose.
The severity of symptoms varies, depending on the amount of lactose an individual can tolerate, the amount of lactose ingested, and the size and fat content of the meal. People who also have irritable bowel syndrome tend to have more severe symptoms from lactose intolerance.
Symptoms are not the same for each person, but common symptoms of lactose intolerance include:
- Watery, bulky, odd-smelling stools
- Abdominal pain
- Upset belly.
- Diarrhea (loose stool).
- feeling sick
- stomach “growling” or rumbling sounds
The intensity of your symptoms and the time of their appearance depends on the amount of lactose you have consumed. Your symptoms may be mild or severe, depending on how much lactose you have. There are people who may still be able to drink a small glass of milk without any symptoms, while others may not even be able to have milk in their tea or coffee.
