How Do I Know If I Have Lactose Intolerance? - Allergy Test

We’re going to be honest with you. It’s incredibly likely that you are lactose intolerant. According to the National Digestive Diseases Information Clearinghouse, 30 to 50 million Americans are lactose intolerant. If you’re African American or American Indian, it is even more likely, with up to 75% of people in these ethnic groups believed to be lactose intolerant. Surprised by this, well, it gets starker for Asian Americans; 90%. See why we’re so confident now? But, there are obviously some people for whom lactose consumption isn’t a problem. So how do you know whether you’re one of the unlucky ones? What are the symptoms of lactose intolerance?


Joey’s turkey pants in Friends. Remember how he put his elasticated pants on to be able to eat more turkey at Thanksgiving? He was probably anticipating bloating that would restrict his ability to load up on protein goodness. When you eat a lot of food, your stomach expands to facilitate the extra. It can be an uncomfortable experience, but can usually be mitigated by not eating more food than you need to. But for people with lactose intolerance, a glass of milk can leave them experiencing this same bloated feeling. Not ideal when you’ve not even eaten yet. This is because their body is unable to produce sufficient quantities of the enzyme lactase, which is required for your body to break down lactose. In their absence, bacteria break it down, and they produce much more gas than enzymes do. This is one of the most common symptoms of lactose intolerance.

Diarrhea, as well as being embarrassing, can cause dehydration and electrolyte imbalance. It is caused by your body detecting a food intolerance and acting to remove it from your system quickly, to do this it draws water from cells into the digestive system where it mixes with stool to make diarrhea.

Stomach Cramps and Pains

All three of these symptoms of lactose intolerance have something in common; they all affect the digestive system. And this particular one is undoubtedly contributed to by the previous two.

Equally, diarrhea can inflame and aggravate the lining of the digestive system, which can also be incredibly painful.
