Unexpected Weight Changes Not Connected to Diet and ExerciseUnexplained weight changes can be signs of both hypothyroidism or hyperthyroidism.Are you on a low-fat, low-calorie diet with a rigorous exercise program, but you're failing to lose weight. Or maybe you're even gaining weight? Or, have you joined a diet program or support group, such as Weight Watchers, and you are the only one who isn't losing any weight? If eating well and exercise are not budging the scale, you have a common symptom of undiagnosed or poorly treated hypothyroidism, an underactive thyroid. On the opposite end, are you losing weight while eating the same amount of food as usual? Has your appetite increased substantially, but you're not gaining weight, or even losing weight? Unexplained weight loss, or higher caloric intake without weight gain are common symptoms of undiagnosed or undertreated hyperthyroidism, an overactive thyroid.Note, however, that some of you may have an opposite response. You could be hypothyroid patients and lose weight, can't gain weight, or are underweight. Or, you may be hyperthyroid patients and find that you can't lose weight, even with a healthy diet and exercise.Learn more about the connection between thyroid problems and weight issues.3.

Hair Loss, Hair Changes, and Skin ChangesHair and skin are particularly vulnerable to thyroid imbalances. In particular, hair loss is frequently associated with thyroid problems. With hypothyroidism, your hair may become brittle, coarse and dry, break easily, and fall out more easily or heavily. In hypothyroidism, there is also a unique and very specific symptom: The loss of hair in the outer edge of the eyebrow. Your skin can become thick, dry, and scaly, especially on heels, knees, and elbows.With hyperthyroidism, severe hair loss can also occur. Your hair may also become fine and thin. Your skin may become fragile, easily irritated, or unusually smooth.There are also two unusual rashes associated with hyperthyroidism and Graves' disease. Pretibial myxedema—also known as thyroid dermopathy—can appear on the skin of the shins. And a bumpy rash known as milaria can appear on the face.6. Constipation, Bowel Problems, Diarrhea, and Irritable BowelA variety of digestive issues can be symptoms of an undiagnosed or undertreated thyroid condition.Severe or long-term constipation, and constipation that does not respond to treatments and remedies, is commonly associated with hypothyroidism.

Diarrhea, loose stools, and irritable bowel syndrome (IBS) are frequently associated with hyperthyroidism.7. Menstrual Irregularities and Fertility ProblemsMenstrual changes are common in thyroid patients.Heavier, more frequent, and more painful periods are frequently associated with hypothyroidism.Women with hyperthyroidism often experience shorter, lighter or infrequent periods. In some cases, periods stop entirely.Women with undiagnosed or improperly treated thyroid conditions—hypothyroidism in particular—are also at higher risk of infertility, failed assisted reproduction treatments, and recurrent miscarriage.8. Muscle and Joint Pains, Carpal Tunnel, Tendonitis, and Plantar FasciitisPain is a common but often overlooked symptom of underlying thyroid issues.People with hypothyroidism may experience aches and pains in muscles and joints, especially the arms and legs. Fibromyalgia-like pain is also common for people with an underactive thyroid.There is also a greater risk of developing carpal tunnel syndrome in the arms/hands, which can cause weakness and pain in the forearms, wrists, hands, and fingers. A similar condition, tarsal tunnel, is also a risk, causing weakness and pain in the shins, ankles, feet and toes. Similarly, a painful foot condition known as plantar fasciitis in the feet.People who are hyperthyroidism may have pain or unusual weakness in the upper arms, and calves.For more information about pain associated with various thyroid conditions, read Muscle and Joint Pain With Thyroid Disease.9. High Cholesterol, Unresponsive to Cholesterol MedicationsHigh cholesterol levels, especially when they are not responsive to diet, exercise or cholesterol-lowering medications such as statin drugs, can be a sign of undiagnosed hypothyroidism.Unusually low cholesterol levels that do not correlate with diet, weight, and exercise may be a sign of hyperthyroidism.10. Eye Problems and ChangesA number of eye-related symptoms and changes are common in hypothyroidism, hyperthyroidism, and Graves’ disease, but can also be due to a related condition, known as Graves’ ophthalmopathy or thyroid eye disease.These include:Your eyes feel gritty and dry.Your vision is blurry.Your eyes are red, dry, swollen, puffy, or watery.Your eyes are sensitive to light.You are having double vision.Your eyeballs appear to be bulging (proptosis); your eyes aren’t completely covered when your eyelids are closed.You have “lid lag," when your upper eyelid doesn't smoothly follow downward movements of the eyes when you look down.What Are Your Next Steps?If you have any of these common symptoms, your next step is to consult a healthcare practitioner for a complete thyroid evaluation.Sources:Bahn R, Burch H, Cooper D, et al.
