Anemia is a serious condition that can cause fatigue and weakness and lead to heart problems or other health issues. However, anemia can be treated, allowing people to regain their independence and live healthier, more productive lives. The symptoms of anemia may vary depending on its type, cause, and any underlying medical conditions, and specific symptoms of conditions like hemorrhaging, ulcers, menstrual issues, or cancer could be noticed before anemia symptoms. The body can also compensate for mild or long-term anemia, so some people may not notice any symptoms.
