You may be hyperthyroid if you’re experiencing some of the common — and lesser-known — signs and symptoms of an overactive thyroid. Learn about these signs and symptoms now.
You are having insomnia and sleep problems
Hyperthyroidism can cause insomnia and sleep problems. You may find it hard to fall or stay asleep, or you may wake up frequently or earlier than you planned. You may also find that the lack of sleep leaves you feeling especially fatigued. If you’re having insomnia or sleep problems, you may be hyperthyroid.
You are losing weight, or can’t gain weight
Hyperthyroidism can cause weight loss, even without a change to your diet or exercise. An overactive thyroid can also make it difficult to gain weight, even after you have increased calories and/or reduced your amount of exercise. If you’re losing weight inexplicably, or unable to gain weight, you may be hyperthyroid.
You are anxious, having panic attacks, depressed, or moody
Heat sensitivity is linked to hyperthyroidism. Hyperthyroidism can make you feel acutely sensitive to and intolerant of hot temperatures. You may also find yourself sweating more than usual. If you feel hot when everyone else feels warm, or if you’re wearing short sleeves when everyone else needs a coat, you may be hyperthyroid.
You have pain, aches, or weakness in your arms and legs
Hyperthyroidism is linked to several types of rashes. You may develop red bumps resembling heat rash on your face (miliaria). You may also develop a rough, bumpy rash on your shins called pretibial myxedema. If you notice either of these symptoms, you may be hyperthyroid.
