Constipation
Constipation is characterized by reduced bowel movement and difficulty passing stool. It is not a disease by itself, but a sign of underlying problems. Hypothyroidism can cause digestive problems, such as constipation.
Hypothyroidism slows down many of your body’s processes. Sometimes, this includes your ability to digest food and eliminate stool. [11] Constipation due to an underactive thyroid is usually due to reduced gut motility.
Conclusion
Hypothyroidism can be hard to spot at the onset. This is because most cases are mild and the symptoms are subtle. Your body’s natural processes change as you get older, so it can be a bit difficult differentiating what is normal from what is not. If you suspect you have an underactive thyroid, speak to a doctor.
