A stroke occurs when blood flow to the brain is cut off, either by a blockage (ischemic stroke) or bleeding (hemorrhagic stroke). Although it often happens suddenly, the body may give warning signs weeks or even months before. Recognizing these signs can help prevent a life-threatening event.
Common warning signs before a stroke
- Fatigue and weakness
Unexplained fatigue or weakness can be an early sign. This happens when blood flow to the brain is reduced, affecting energy levels and physical strength.
- Frequent headaches
Frequent headaches, especially those that are severe or different from usual, may indicate underlying problems with the blood vessels in the brain.
