Why Do I Feel So Tired and My Legs Feel Weak?

Poor circulation

Your legs may feel tired or fatigued if your blood isn't circulating through your body properly. Poor circulation often affects the lower part of your body since it's harder for blood to flow upward toward your heart. Sometimes blood can collect in your legs, ankles, and feet.

What causes leg weakness and fatigue?

Muscle weakness is commonly due to lack of exercise, ageing, muscle injury or pregnancy. It can also occur with long-term conditions such as diabetes or heart disease. There are many other possible causes, which include stroke, multiple sclerosis, depression, fibromyalgia and chronic fatigue syndrome (ME).

What causes heavy legs and tiredness?

Without enough blood circulating, your legs can feel tired, crampy, and achy. These symptoms are one of the first signs of PAD. The same things that cause fatty buildup in your other arteries cause them in your legs as well. High cholesterol, smoking, diabetes, and high blood pressure are top risk factors.
