Constipation
Low levels of thyroid hormones also cause some issues on your colon. In fact, nearly 20% of people with hypothyroidism experience mild to severe constipation. While this is a common symptom of the issue, it isn’t common for constipation to be the most serious or only sign. This means if you have constipation but also feel fine, then it is better to consider some natural laxatives before starting to be worried about your thyroid. In case they do not work and your constipation gets worse, such as vomiting or passing tool, it is advisable to consult your doctor immediately. [2]
