A study published in BMC Medicine found that controlled phlebotomy (blood removal) significantly lowered systolic blood pressure by an average of 18 mmHg and improved cholesterol ratios in patients with metabolic syndrome. Excess iron contributes to oxidative stress, inflammation and insulin resistance, worsening conditions like high blood pressure, diabetes and heart disease. Reducing iron stores through phlebotomy may alleviate these risks. Participants who underwent phlebotomy showed notable improvements in fasting glucose and HbA1c levels, though insulin sensitivity changes were minimal – possibly due to the study’s short duration (six weeks). Past research suggests frequent blood donors have lower heart attack risk, better insulin…
