Not Sleeping Well? There May Be a Medical Cause

Thyroid disease
An overactive thyroid gland (hyperthyroidism) can cause sleep-busting night sweats, while an underactive thyroid gland (hypothyroidism) brings on excessive daytime sleepiness. Both of these thyroid conditions can be diagnosed with a simple blood test and easily treated with medications.When sleep problems are due to a medical problem or physical condition, treating the condition will often resolve the insomnia and ease sleep disturbances, says Wellman. See your doctor for an evaluation, and you may find that your insomnia does a disappearing act. If not, the next step is to make an appointment with a sleep specialist.
