Lightheadedness and fatigue are very common non-specific symptoms that can be caused by many medical conditions. Some clues can help point to one medical condition or another, I will try to explain some of these clues here.

Everybody feels tired after a long day at work but sometimes fatigue becomes chronic and lasts for a long period. Most of the people seek medical attention concerning about chronic fatigue. Fatigue could be caused by almost any medical condition that's why it is considered one of the most difficult symptoms to manage if presented without other symptoms. Some of the common causes of fatigue include but are not limited to:

  • Alcohol abuse
  • Excessive caffeine use: caffeine activates your neurons and helps you be more alert and focused but if you drink coffee everyday your neurons will get used to the caffeine dose and will require more and more as a result you will feel tired. Although has not yet been proven the best way to deal with this issue is to allow 1-2 coffee free days.
  • Inactivity
  • Prescriptional and non-prescriptional medications.
  • Lack of sleep or ineffective sleep. One of the common causes of ineffective sleep is a sleep apnea that is basically a cessation of breathing multiple times during your sleep for 10 seconds each time. Sleep apnea is characterized by unrefreshing sleep and snoring. Sleep apnea should be treated to avoid its complications.
  • Unhealthy diet, especially the lack of fresh fruit and vegetables.
  • Hepatitis: your eyes and skin turn yellow, and your pee turns dark.
  • Anemia: sometimes anemia is very obvious that it can be recognised because of pale hands.
  • Cancer: symptoms that are common among most of the types of cancer include fatigue, weight loss, loss of appetite.
  • Kidney failure.
  • Heart disease.
  • Hormonal imbalances
  • Diabetes
  • Anxiety
  • Stress
  • Depression: very common cause of fatigue and should be treated with the proper medication.

Lightheadedness can be defined as the feeling that you are going to pass out. One of the important characteristics of lightheadedness is that it often goes away when you lie down. Sometimes lightheadedness is so severe that it can cause fainting. Lightheadedness is also commonly associated with vomiting and nausea.

Usually lightheadedness is nothing to worry about and rarely it is caused by a serious problem. Usually lightheadedness happens if you suddenly stands up from lying or sitting position. What happens is that when you lie for a while the blood pools in the veins and the heart decreases its pumping capacity since it doesn't need to pump blood against gravity; when you stands up it takes the heart a few moments to catch up with the extra workload that is caused by the gravity. As a result the brain will not get enough blood for a short moment you feel this as lightheadedness and darkening in front of your eyes.


  • Flu and colds
  • Allergies
  • Dehydration
  • Anxiety: Is associated with rapid breathing, lightheadedness, numbness around the mouth and can even lead to fainting.
  • Migraine: Lightheadedness is a common symptom of migraine. It can present with or without headache, sometimes migraine has warning symptoms such as flashing lights in front of your eyes or shining circles around bright objects.
  • Neurological conditions such as Multiple Sclerosis which can cause both fatigue and dizziness in addition to other neurological symptoms such as vision problems and pain behind one eye.
  • Alcohol and some of the abused substances.
  • Bleeding: This is a serious cause. The source of bleeding must be sought and identified. Bleeding can be caused by another serious medical conditions such as cancer.
  • Many prescriptional and over the counter medications can cause lightheadedness.
