Top 10 Hunger Causes
1.Diabetic Hypoglycemia
Hypoglycemia (severely low blood sugar) can occur in Type 1 (more common) and Type 2 Diabetes. It is usually caused by poorly timed use of blood-sugar-controlling medication.
Severely low blood sugar is extremely dangerous. You need to go to the ER immediately, where blood tests to assess your blood sugar will be done quickly and stabilized immediately if found to be low.
- Rarity:
- Uncommon
- Top Symptoms:
- fatigue, irritability, anxiety, racing heart beat, dizziness
- Symptoms that always occur with diabetic hypoglycemia:
- being severely ill
- Urgency:
- Hospital emergency room
2.Viral (Norovirus) Infection
Noroviruses are a group of related viruses that leads to nausea, vomiting, diarrhea, and cramps. These viruses cause gastroenteritis, an inflammation of the stomach and intestines. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.
You can safely treat this condition at home. Make sure you drink plenty of water and fluids (Gatorade, Pediatlyte) to replace what is lost with diarrhea. If symptoms of dehydration occur or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.
- Rarity:
- Common
- Top Symptoms:
- fatigue, abdominal pain (stomach ache), nausea, headache, stomach bloating
- Symptoms that always occur with viral (norovirus) infection:
- hidden: gastroenteritis symptoms
- Symptoms that never occur with viral (norovirus) infection:
- severe abdominal pain, throbbing headache, severe headache, tarry stool
- Urgency:
- Self-treatment
3.Viral (Rotavirus) Infection
Rotavirus is a virus that causes an infection of the gut, known as gastroenteritis. Symptoms include diarrhea, vomiting and fever. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.
You can safely treat this condition at home. Make sure you drink plenty of water and fluids to replace what is lost with diarrhea. Eat as normally as possible. If symptoms of dehydration occur, or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.

4.Normal Variation of Constipation
Constipation is a very common condition affecting the large intestine. It is characterized by difficulty passing stool, or passing stool less often. Commonly it is linked to not eating enough dietary fiber, not drinking enough fluids, or not getting enough exercise. Some medications can cause constipation as well.
For the short term, an over-the-counter laxative can help with your constipation. You can try to make changes at home to help prevent these symptoms. Dietary changes are typically effective: drink more fluids and eat more fiber (found in bran, root vegetables, nuts, and whole-grain flour). There are also over-the-counter fiber tablets that can help increase your dietary fiber.

5.Obstructive Sleep Apnea
Sleep apnea is a disorder in which the upper airway is obstructed during sleep, which causes poor sleep quality and frequent awakening.
You should visit your primary care physician within a few weeks to discuss your symptoms. The physician will likely order a sleep test to confirm the diagnosis.

6.Recurrent Migraine
Migraines are headaches of moderate to severe intensity, which happen when blood vessels in the brain swell up. They are episodic and thus can recur often. Most migraine sufferers experience increased sensitivity to sounds and/or lights and become nauseous and vomit.
Migraines are diagnosed purely by your symptoms. Talk to a doctor if you have two or more migraines each month, as there are more effective treatments for preventing migraines. Medications, such as over-the-counter pain killers (e.g., ibuprofen or Tylenol) may help. However, it is important not to take them too regularly. Taking them more than two or three times a week can cause more headaches, as the body gets used to the drug, and the headache comes back when you stop taking the medication.
- Rarity:
- Common
- Top Symptoms:
- headache, fatigue, history of headaches, nausea, mild headache
- Symptoms that always occur with recurrent migraine:
- headache, history of headaches
- Symptoms that never occur with recurrent migraine:

8.Common Cold
The common cold is a viral infection of the upper respiratory tract.
The common cold is treated symptomatically. Since this is a viral infection, antibiotics are not effective. You can safely treat the symptoms of this condition with over-the-counter pain relievers, decongestants, antihistamines & cough medicines.
- Rarity:
- Common
- Top Symptoms:
- fatigue, headache, cough, sore throat, congestion
- Symptoms that never occur with common cold:
- being severely ill, severe muscle aches, rash, severe headache
- Urgency:

9.Low Blood Sodium
Hyponatremia is a deficiency in sodium. Sodium is one of the most important nutrients in the body, needed for nerves to conduct signals, muscles to contract, and blood pressure to be maintained at safe levels, etc. A deficiency in sodium can cause severe, widespread symptoms.
You need to seek care immediately. A walk-in clinic will likely be able to help bring your sodium levels back up to normal levels safely.
- Rarity:

- Top Symptoms:
- fatigue, nausea, headache, abdominal pain (stomach ache), loss of appetite
- Urgency:

10.Overactive Thyroid
The thyroid is a butterfly-shaped gland in the neck, just above your collarbone. It is one of your endocrine glands, which make hormones. Thyroid glands control how fast one burns calories and how fast the heart beats. If the thyroid is too active, it makes more thyroid hormones than the body needs. This is called hyperthyroidism.
You should visit your primary care physician, who might take a blood test to measure your levels of thyroid hormone. The test will tell the doctor whether a referral to an endocrinologist is useful. Treatment plans would likely be set by the specialist and include drugs to reduce your thyroid activation.
