I think the calls to donate blood on TRT are unfounded I have never donated blood
“Thickened blood, or increased blood viscosity, can occur as a side effect of injectable testosterone because it can stimulate an increase in red blood cell production, leading to elevated hematocrit and hemoglobin levels. Here’s how this could impact blood pressure, heart rate, and other vitals:
1. Blood Pressure:
• Increased blood thickness makes it harder for blood to flow through the vessels, which can increase vascular resistance and, in turn, raise blood pressure.
• This may be especially noticeable if someone already has borderline or high blood pressure before starting testosterone therapy.
2. Heart Rate:
• The heart may need to work harder to pump thicker blood, which can sometimes result in a higher resting heart rate.
• In some cases, the heart may experience more strain, leading to an increased risk of cardiovascular issues over time if the blood viscosity remains elevated.
3. Other Symptoms:
• Headaches and dizziness: Thicker blood can reduce oxygen delivery to certain areas, potentially leading to headaches or lightheadedness.
• Fatigue: Increased blood viscosity can limit how efficiently oxygen is delivered to tissues, which may cause feelings of fatigue or sluggishness.
• Red or flushed appearance: Higher hematocrit levels can lead to a flushed or ruddy complexion.
• Shortness of breath: Reduced oxygen circulation can sometimes make breathing feel more labored.
4. Potential Risks:
• Risk of blood clots: Elevated red blood cell counts can increase the risk of clotting, which can lead to conditions like deep vein thrombosis (DVT), pulmonary embolism, or stroke.
• Thrombosis: The higher clotting risk can strain the cardiovascular system, and over time, thick blood can lead to complications, especially in arteries or veins prone to blockage.”
