While many factors can contribute to feeling tired, a deficiency in vitamin B12 is known to cause fatigue and sleepiness.
Vitamin B12 plays a crucial role in the production of red blood cells, which carry oxygen throughout your body. A lack of B12 can lead to a decrease in red blood cell production, resulting in a condition called pernicious anemia. This anemia can cause fatigue, weakness, and shortness of breath, all of which can make you feel sleepy.
Other symptoms of vitamin B12 deficiency include:
- Numbness or tingling in your hands and feet
- Difficulty walking
- Memory problems
- Depression
If you suspect you might have a vitamin B12 deficiency, it's essential to consult with your doctor for diagnosis and treatment. They can perform a blood test to check your B12 levels and recommend appropriate supplements or dietary changes.
