Why Am I Always Hungry?

Your body relies on food for energy, so it’s normal to feel hungry if you don’t eat for a few hours. But if your stomach has a constant rumble, even after a meal, something could be going on with your health.

The medical term for extreme hunger is polyphagia. If you feel hungry all the time, see your doctor.

Several things can cause hunger.
1. Diabetes
Your body turns the sugar in food into fuel called glucose. But when you have diabetes, glucose can’t reach your cells. Your body pees it out instead and tells you to eat more.

People who have type 1 diabetes, in particular, may eat large amounts of food and still lose weight.

In addition to a spike in your appetite, symptoms of diabetes may include:

  • Extreme thirst
  • The need to pee more often
  • Weight loss you can’t explain
  • Blurry vision
  • Cuts and bruises that take a long time to heal
  • Tingling or pain in your hands or feet
  • Fatigue

2. Low Blood Sugar
Hypoglycemia is what you have when the glucose in your body drops to very low levels. It’s a common concern for people with diabetes, but other health problems can cause it, too. They include hepatitis, kidney disorders, neuroendocrine tumors in your pancreas (insulinomas), and problems with your adrenal or pituitary glands.

In severe cases, people with hypoglycemia may seem drunk. They may slur their words and have trouble walking. Other symptoms can include:

Anxiety
Feeling like your heart is skipping a beat
Pale skin
Shaking
Sweating
Tingling around the mouth
3. Lack of Sleep
Not getting enough rest can affect the hormones in your body that control hunger. People who are sleep-deprived have a bigger appetite and find it harder to feel full. You’re also more likely to crave high-fat, high-calorie foods when you’re tired.

Other effects of sleep deprivation include:

A hard time staying alert
Change in mood
Clumsiness
More accidents
Trouble staying awake during the day
Weight gain
4. Stress
When you’re anxious or tense, your body releases a hormone called cortisol. This amps up your feeling of hunger.

Many people under stress also crave foods high in sugar, fat, or both. It may be your body’s attempt to “shut off” the part of your brain that causes you to worry.

Other symptoms include:

Angry outbursts
Fatigue
Headache
Sleep problems
Upset stomach
5. Diet
Not all foods fill you up the same way. The ones that curb hunger best are high in protein — like lean meats, fish, or dairy products — or high in fiber. Good sources of fiber are fruits, vegetables, whole grains, and beans.

Healthy fats like those found in nuts, fish, and sunflower oil can lower your cholesterol levels. They’re key to a balanced diet and can help you feel satisfied after you eat.

Pastries, white bread, many packaged meals, and fast foods lack these nutrients but are high in fat and unhealthy carbs. If you eat a lot of these, you could find yourself hungry again soon after a meal. You may eat more than you should.

You might feel fuller after a meal if you take more time to chew and enjoy your food, rather than eating it quickly. It can also help to pay attention to what’s on your plate instead of the TV or your phone.
6. Medication
Some drugs can make you want to eat more than usual. Antihistamines, which treat allergies, are known for this, as are antidepressants called SSRIs, steroids, some diabetes medicines, and antipsychotic drugs.

If you’ve gained weight since you started a medication, the medicine could be making you feel hungry. Talk to you doctor to find out what other drugs might work for you.
