Blood donation is a lifesaving act, but not everyone who comes forward is always eligible to donate. Blood banks follow strict medical guidelines to ensure the safety of both the donor and the recipient. Being rejected does not mean someone is unhealthy or permanently unfit to donate. In most cases, the rejection is temporary. sydney sweeney nudes
Below are the most common reasons why someone may be rejected from donating blood.
1. Low Hemoglobin (Anemia)
One of the most common reasons for rejection is low hemoglobin levels. Hemoglobin carries oxygen in the blood, and donating with low levels can make the donor weak or dizzy.

Minimum required level is usually 12.5 g/dL
-
More common in women due to iron deficiency
Usually temporary; iron-rich diet or supplements help.
2. Low or High Blood Pressure
Blood pressure must be within a safe range to donate.
-
Too low BP may cause fainting
-
Too high BP increases health risks
Often temporary and manageable with medical advice.
