What are the complications of untreated severe anemia?

Untreated anemia can lead to several complications, including:

1. Fatigue and weakness: Decreased red blood cells and hemoglobin levels can cause persistent fatigue, weakness, and shortness of breath.

2. Poor immune function: Anemia can impair the immune system, making you more susceptible to infections.

3. Poor wound healing: Inadequate oxygen delivery to tissues can impede wound healing.

4. Hair loss: Iron deficiency anemia can cause hair loss due to reduced oxygen supply to hair follicles.

5. Restless leg syndrome: Iron deficiency can lead to restless leg syndrome, causing discomfort and pain.

6. Poor cognitive function: Anemia can impair cognitive function, memory, and concentration.
