Eating is essential to survival, but if you're not hungry nothing is appetizing. A loss of appetite may be the result of emotional upset, depression or a medical condition. In combination with your doctor's care, some remedies and lifestyle changes may act as appetite stimulants. Consult your physician if you are losing weight without dieting or if your loss of appetite lasts more than a day or two.
Function
When the body is functioning normally, the aroma of food can trigger the desire to eat, according to Psychology Today. Your brain conjures up a mental image of a favorite food and you may salivate in anticipation of a bite. Other appetite triggers include hearing a lunch bell, reduced blood sugar levels in the body or a nerve impulse in your mouth that makes you crave a specific taste, like salty chips or sweets.
Causes
An eating disorder, like anorexia nervosa, may result in a loss of appetite, but there are other causes as well. Cancer, chemotherapy, kidney or liver disease, an infection, a thyroid disorder or even pregnancy may result in a reduced appetite, according to the New York Times Health Guide. Depression is another cause of appetite loss, especially in the elderly.
Stimulants
Some herbs and supplements may stimulate the appetite, although clinical studies confirming their benefits are lacking. Potentially beneficial herbs include alfalfa, dandelion, hyssop and yarrow, according to Herbs 2000. Dietary supplements, such as vitamins A, C, E and B-complex may also help. A deficiency in zinc or folic acid may reduce the appetite and taking these minerals in supplementary form may restore a healthy appetite. Consult your doctor before using any herb or supplement to treat a medical condition.
Lifestyle Changes
Changing the way you eat and view food may stimulate a decreased appetite, according to the Mayo Clinic. Keep meals small to avoid a stuffed feeling, but eat frequently during the day. If you're suffering from lack of appetite, don't put off eating; keep nutritious, high-calorie snacks on hand for quick munching. Make meals inviting by using attractive place settings, soothing background music and candles. Avoid drinking fluids before and during the meal to prevent filling up on liquids.
Complications
Without intervention, loss of appetite may lead to weight loss and muscle wasting. See your doctor to rule out an underlying disorder related to your loss of appetite.
