Recommend eval: I don’t know what is causing your symptoms but fatigue, constipation, weight gain, increased cold sensitivity & muscle aches may be seen with hypothyroidism. It can also impact cognition. Chronic, untreated hypothyroidism can effect periodontal health. An unexplained 35 pound weight gain over a brief period of time isn't normal. Recommend medical evaluation to help make sense of these symptoms.
