Always Hungry? You Just Might Have One Of These Conditions

Medically reviewed on Jun 13, 2017 by C. Fookes, BPharm

Overactive Thyroid, Overactive Appetite

Your thyroid gland is located in the front of your neck, just above where your collarbones meet. This important gland makes hormones that control metabolism (the way every cell in your body uses energy). Changes in the way it functions affect your mood, weight, and energy levels. The most common reason for an overactive thyroid is Graves disease. Graves disease stimulates the thyroid gland to increase its output of thyroid hormones. Symptoms include hunger as well as a rapid heartbeat, sweating, an enlarged neck and tiredness. See your doctor if you have any of these symptoms for further tests.

Constantly Fueling Your Fight Or Flight

We humans have a built-in emergency alert system. Nicknamed "fight-or-flight", it triggers to a perceived harmful event, attack, or threat to our survival. Activation results in a massive release of cortisol and other hormones that allow us to fight or flee the situation. One problem: constant stress or anxiety makes this fight-or-flight response hyperactive. High levels of cortisol all day, every day, make us hungry and promote weight gain; not to mention this also undermines our immune system. So, if you're stressed and hungry, stop! Re-evaluate your life and make it a top goal to minimize stress. Cushing Syndrome is also due to high levels of cortisol.

Sugar In The Blood - Not In The Cell - Causes Hunger

Diabetes is a condition in which there is too much sugar (glucose) in your blood. There are three main types:

  • Type 1: Most commonly diagnosed in children aged seven to 12, although it can occur at any age.
  • Type 2: Usually affects middle-aged or older people with excess weight.
  • Gestational diabetes: Found in pregnancy with a screening test; in most women, it goes away after pregnancy.

Symptoms include increased hunger, excessive thirst and frequent urination; see your doctor if you suspect diabetes.

Low Blood Sugar Can Also Cause Hunger Pangs

The last slide talked about how high blood sugar levels make you hungry. Oddly enough, low blood sugar levels (hypoglycemia) can cause hunger, too. In adults and children older than 10 years, hypoglycemia is uncommon, except as a side effect of diabetes treatment. In people with diabetes, hypoglycemia can happen suddenly, but is usually mild and can be easily treated by eating or drinking a small amount of sugar-rich food. If left untreated, blood sugar levels drop even further and can cause confusion, clumsiness, and fainting. Severe hypoglycemia can lead to seizures, coma, and even death.

Eating When You Are Sad

Research has shown that eating releases serotonin, the "Feel Good" hormone. Some people may turn to food when they're feeling a bit blue or when things aren't working out as planned.

But food generally only provides a short-term boost. If you have been feeling sad or irritable most days, for a few weeks now, you may have depression. Talk to your doctor about how you are feeling. Try to get back on track with your diet as gaining weight is not the right pathway to a better mood, and can adversely affect your health in other ways, too.

Unwanted Extras In Your Intestines: Worms

In the U.S. pinworm (also called threadworm) is the most common worm infection. Although it mainly affects school-age children, it is easy to catch so adults in family groups may also find themselves affected, and may need treatment.

Most people actually have no symptoms, but some people may feel tired, have a hunger-like feeling in their stomach or an itchy bottom. Treatment is simple and pyrantel (Pin-X, Reeses Pinworm) is readily available at your pharmacy.

The most likely worm to cause hunger-pangs are tapeworms; however, these are rare in the U.S.

Use Caution With The Fridge If You're Pregnant

Most women develop a ravenous appetite during the second trimester of pregnancy (around week 17), as the baby develops and demands more nourishment. But keep in mind portion sizes. Although technically you are eating for two, your baby is a lot smaller than you are and too much weight gain during pregnancy can be detrimental. The U.S. Institute of Medicine recommends a weight gain of no more than one pound per week during the second and third trimester of pregnancy; less if you are overweight before pregnancy.

Food Cravings Before That Time Of The Month

Almost three out of four women experience premenstrual syndrome (PMS) symptoms during their childbearing years. Food cravings and an increased appetite can be a sign of PMS in addition to feeling bloated or having gas pains, and experiencing breast tenderness, irritability and tiredness.

If you are a woman and find you get hungry only during certain times of the month, you may be experiencing PMS. Exercise and a healthy diet can help relieve symptoms. See a doctor if your PMS affects your quality of life or does not go away with self-help measures.

Could Your Meds Be Making You Hungry?

In a cruel twist of fate, many drugs that are used to treat obesity-related conditions can also cause weight gain. Examples include insulin and beta-blockers. Weight gain may also associated with birth control pills, corticosteroids like prednisone, and certain mood medicines like Abilify, Clozaril, Depakote, Paxil, Prozac, Seroquel, or Zyprexa. DO NOT STOP taking your medicines because of this side effect. Talk with your doctor about monitoring your weight from the moment you start taking any of these medicines. And remember: eat a healthy diet and exercise, too.

How Commonly Does Cancer Cause Hunger?

In general, cancer tends to suppress your appetite and make you feel less hungry. Often this is accompanied by a rapid weight loss.

But certain tumors, such as glucagonomas (a type of tumor in the pancreas) can raise blood sugar levels and cause hunger.

If you are hungry all the time but still losing weight despite eating large quantities of food, see your doctor for further tests.

When Hunger is Due to Exercise But You Exercise To Lose Weight

The formula for weight loss sounds easy: Exercise + Diet = Pounds Off.

Sounds easy...but is never that easy. The trouble is, exercise tends to make us hungry, as our bodies start to crave the energy we have used up.

Experts believe that more frequent exercising eventually resets your hunger signals. In the meantime, avoid snacking after exercise "Because you deserve it!" Bear in mind that even an intense workout lasting 45 minutes burns less than 100 extra calories, so don't negate all that hard work for one candy bar reward.

What You Eat And How You Eat: It Does Make A Difference

Ok...so this isn't strictly a condition, but it could be the reason you are still hungry after a meal.

High sugar foods are easily absorbed by the body and taken up by our cells with the help of insulin. However, this energy is quickly burned leaving us still hungry. Foods that are protein-rich (like fish or beans) or whole grains naturally make us feel fuller. Hot foods and soups are also more stomach-satisfying than cold foods. Water also helps fill you up so always drink a glass or two with your meal. Chew and eat slowly to give your stomach time to tell your brain that it is full.
