Other Symptoms
While gastrointestinal problems are the most common lactose intolerance symptoms, certain case studies have noted additional symptoms, such as:
- Headaches
- Fatigue
- Loss of concentration
- Muscle and joint pain
- Mouth ulcers
- Problems urinating
- Eczema
- ...
These signs may be caused by various conditions and have not yet been proven to be lactose intolerance symptoms. Additionally, some patients who have a milk allergy could mistakenly mistake lactose intolerance for their symptoms. In fact, cow's milk allergies are more prevalent in children and affect up to 5% of the population. Lactose intolerance and milk allergy are unrelated. It's critical to accurately diagnose symptoms, especially in children, because a milk allergy can be severe as opposed to lactose intolerance.
