Frequent headaches and feeling tired can be caused by a variety of common conditions. According to the Mayo Clinic, some of the common conditions that can cause frequent headaches and feeling tired include dehydration, hypoglycemia--low blood sugar--and chronic fatigue syndrome. If you experience two or more headaches a week, your headaches get worse or you're tired more than normal, contact your health-care provider.
If you aren't drinking enough water, you may experience frequent headaches and chronic bouts of fatigue. According to the Mayo Clinic, dehydration develops when your body loses more fluids than it takes in. If your body doesn't have enough water or fluids to carry out its normal functions, you may experience dehydrated related symptoms. Other symptoms include dry mouth, thirst, decreased urination, muscle cramping and weakness. One visual sign of dehydration is the color of your urine. Clear or light-colored urine signifies that your body is well-hydrated. Dark yellow, orange or amber urine usually means you're dehydrated. Not having enough water and fluids in the body can have serious consequences. Common reasons dehydration occurs may be excess sweating, vomiting or diarrhea. Mild to moderate dehydration can be treated by simply taking in more fluids. Severe dehydration requires intravenous hydration to quickly deliver fluids and essential nutrients to the body.
Hypoglycemia occurs when your body is low on glucose--blood sugar. According to the University of Maryland Medical Center, some of the main instances of low blood sugar occur when you don't take in enough food, you increase exercise without increasing the amount of calories you take in or you take too much insulin or diabetic medication. Symptoms of hypoglycemia include headaches, fatigue, hunger, rapid heart rate and irritability. If you let hypoglycemia go untreated for too long, you may experience more severe symptoms, such as profuse sweating, dizziness, feeling faint or loss of consciousness. Hypoglycemia has the potential to be fatal if left unchecked for extended periods of time. Typical treatment requires that you get your blood sugar up as soon as possible by ingesting sugar in the form of candy, fruit juice or glucose tablets. If you are diabetic, an injection of glucagon may be appropriate in certain situations.
Chronic Fatigue Syndrome
Chronic fatigue syndrome may cause frequent headaches and tiredness. According to the Mayo Clinic, in most cases, the cause of chronic fatigue syndrome is unknown, but it is widely accepted as a serious medical condition. Chronic fatigue syndrome is characterized by a constant feeling of tiredness even though you may get enough sleep or rest. Some of the proposed causes for chronic fatigue syndrome include hypoglycemia, depression and anemia. Treatment may include moderating daily activity, gradually beginning an exercise routine and getting treated for any other condition your doctor may feel is contributing to your case of chronic fatigue syndrome.
