Why Am I So Tired?

Everyone feels tired now and then. But, If you continue to feel tired for weeks in a row, it's time to see your doctor. They may be able to help you find out what's causing your fatigue. In fact, your doctor may even suggest you become more active, as exercise may reduce fatigue and improve quality of life.
 
Sometimes, fatigue can be the first sign that something is wrong in your body. For example, people with COPD, often complain of fatigue. People with cancer may feel fatigued from the disease, the treatments, or both. Fatigue can be attributed to many medical conditions including:

• Taking certain medications, such as antidepressants, antihistamines, and pain relivers
• Medical treatments, like chemotherapy, radiation, or major surgery
• Infections
• Chronic diseases like diabetes, heart disease, kidney disease, liver disease, thyroid disease
• Untreated pain
• Anemia
• Sleep apnea

 
Emotional stresses can take a toll on your energy. Fatigue can be linked to many conditions, including:

• Anxiety
• Depression
• Grief
• Stress due to financial or personal issues

Some lifestyle habits can add to fatigue:

• Staying up too late. A good night's sleep is important to feeling refreshed and energetic. Try going to bed and waking up at the same time every day.
• Having too much caffeine. Drinking caffeinated drinks like soda, tea, or coffee late in the day can keep you from getting a good night's sleep. Limit the amount of caffeine you have during the day and avoid it in the evening.
• Drinking too much alcohol. Alcohol changes the way you think and act. It may also interact with your medicines.
• Eating junk food. Avoid food with empty calories, like fried foods and sweets, which are high in fat and sugars. Choose nutritious foods to get the energy you need.
• Being bored. If you were very busy during your working years, you may feel lost about how to spend your time when you retire. Think about what interests you and what skills or knowledge you have to offer and look for places to volunteer.

 
How can I feel less fatigued?
Some changes to your lifestyle can make you feel less tired:

• Exercise regularly. Almost anyone, at any age, can do some type of physical activity. If you have concerns about starting an exercise program, ask your doctor if there are any activities you should avoid. Regular exercise can help improve your sleep and may also help reduce feelings of depression and stress while improving your mood and overall well-being.
• Try to avoid long naps. Long naps especially late in the day can leave you feeling groggy and may make it harder to fall asleep at night.  
• Ask for help if you feel overwhelmed. Some people have so much to do that just thinking about their schedules can make them feel tired. Working with others may help a job go faster and be more fun.

When should I see a doctor for fatigue?
If you've been tired for several weeks with no relief, it may be time to call your healthcare provider. He or she will ask questions about your sleep, daily activities, appetite, and exercise and will likely give you a physical exam and order lab tests. Your treatment will be based on your history and the results of your exam. Your doctor may prescribe medications to target underlying health problems.
