1. Loud snoring

Sleep apnea affects more than 18 million Americans, according to statistics released by the National Sleep Foundation. Those at risk include males, overweight individuals, and people over 40. Signs of sleep apnea include: abrupt nighttime awakenings, difficulty staying asleep, excessive daytime sleepiness, loud snoring, and morning headaches. Untreated sleep apnea is a potentially serious sleep disorder that can lead to depression, heart disease, hypertension, and even stroke.

2. Bad breath

The most common cause of bad breath, or halitosis, is poor dental hygiene. When bacteria build up in the mouth, it forms plaque or tartar on teeth that can lead to gingivitis, a condition characterized by red, inflamed sensitive gums. Untreated gingivitis can progress to periodontal disease. The tissue around the tooth becomes inflamed and the gum pulls away, forming a space called a pocket that becomes infected, resulting in tooth loss in severe cases.

3. Frequent nose bleeds

Nose bleeds are common and rarely life-threatening. They occur most frequently in children and older adults and causes include: allergies or colds, low humidity levels, medications that dry out the nasal passages, minor injuries, nose picking, and structural nasal problems. Only rarely are they caused by a medical condition like an abnormal growth or ruptured blood vessel. Most can be treated at home; however, if you have a blood clotting disorder, you may need to seek emergency medical care.

4. Dry, flaky skin

The thyroid gland is located at the base of the neck, above the collarbone, and produces hormones that regulate the body’s metabolism as well as healthy hair, skin, and nails. One sign the thyroid isn’t producing enough hormones, a condition called hypothyroidism or underactive thyroid, is dry, flaky skin on the backs of the fingers or upper arms. Metabolism affects not only how well the body burns calories but body temperature and heartbeat. If dry, flaky skin persists, see a doctor for a thyroid function test to ensure everything is functioning normally.

5. Loss of eyelashes

A common eye disease is blepharitis, or eyelid inflammation. It is caused by allergies, bacteria, environmental conditions, inflammation, skin cancer, or systemic disease. Symptoms include burning, itching, irritation, and the feeling that something is in the eye. In severe cases, blepharitis results in loss of eyelashes. While not serious, it can be a nuisance but responds well to treatment. See a doctor who will likely prescribe an eyelid hygiene regimen to treat the problem.
