Tiredness and Fatigue

Tiredness and fatigue are common symptoms that can be caused by a variety of factors. They are characterized by a feeling of lack of energy, exhaustion, and a decreased ability to perform physical or mental activities.

Causes of Tiredness and Fatigue

• Anemia: A condition where the body has a low red blood cell count or low hemoglobin levels, leading to inadequate oxygen delivery to tissues and organs.
• Sleep Disorders: Conditions such as insomnia, sleep apnea, and restless leg syndrome can disrupt sleep patterns and lead to tiredness and fatigue.
• Chronic Diseases: Conditions like diabetes, arthritis, and heart disease can cause persistent fatigue due to inflammation, pain, or other underlying mechanisms.
• Hormonal Imbalances: Thyroid disorders, adrenal insufficiency, and menopause can lead to changes in energy levels and fatigue.
• Medications: Certain medications, such as sedatives, antidepressants, and blood pressure medications, can cause drowsiness or fatigue as a side effect.
• Nutritional Deficiencies: Lack of essential nutrients like iron, vitamin B12, or magnesium can contribute to tiredness and fatigue.
