Lactose intolerance affects millions of people worldwide, often without them realizing it. In this article, we'll explore 8 common ways your body might be trying to tell you that lactose intolerance could be the culprit behind your discomfort.
Mouth Ulcers
It’s not as common, but some people with lactose intolerance have also reported symptoms like mouth ulcers. Dairy products such as milk, cheese, and yogurt are often linked to the development of canker sores. Experts believe that proteins found in cow’s milk may trigger mouth ulcers in certain individuals, potentially as an adverse immune reaction to cow’s milk.
If you frequently experience mouth sores, consider eliminating dairy products from your diet and trying alternatives such as soy milk, oat milk, and vegan cheese.
Swelling
Dairy allergies can cause reactions beyond digestive issues, affecting other areas of the body, including the skin and lungs. Common symptoms include:
- Rash
- Hives
- Swelling around the lips and face
- Wheezing
- Tightness in the throat
- Trouble swallowing
In severe cases, anaphylaxis can occur, requiring immediate medical attention and the administration of epinephrine. Learn more about anaphylaxis symptoms and treatment.
Diarrhea or Constipation
Lactose intolerance can lead to digestive issues like diarrhea after consuming dairy products. For some individuals, it may also cause constipation due to methane production slowing intestinal movement. Studies suggest that methane production occurs in about one-third of those affected by lactose intolerance.
Bloating
Bloating is a frequent symptom when the body cannot properly digest lactose due to a lactase deficiency. This causes lactose to ferment in the colon, leading to gas production and bloating.
Headache and Fatigue
Some individuals experience symptoms beyond the digestive system, such as headaches, fatigue, and trouble focusing. This may be due to the body's inflammatory response to undigested lactose.
Flatulence
Undigested lactose in the small intestine is broken down by gut bacteria, producing gases like hydrogen, methane, and carbon dioxide, leading to flatulence.
Muscle and Joint Pain
Muscle and joint pain may result from lactose disrupting the gut microbiome and triggering systemic inflammation. Whether it's due to poor digestion or metabolic impacts, inflammation can lead to discomfort.
Abdominal Pain and Cramps
The most common symptoms include abdominal cramps and pain, usually occurring within hours after consuming dairy products.
