Yes — both excess weight and low body weight can influence your biomarkers across metabolism, inflammation, organ function, and hormonal balance.
Excess weight Carrying excess weight is often associated with insulin resistance, which can show up as elevated Hemoglobin A1c and Insulin levels. It can also contribute to cholesterol imbalances (lower HDL, higher LDL), increased inflammation markers like C-Reactive Protein and Cortisol, and liver strain reflected in elevated ALT, AST, and GGT.
Low body weight Being underweight can have the opposite effect in some areas — lower blood sugar markers (Hemoglobin A1c, Insulin), nutrient deficiencies such as low Vitamin D and Ferritin, and hormonal imbalances including low Testosterone in men and low Progesterone in women.
That said, abnormal biomarkers aren't always caused by weight alone. Diet, sleep, stress, and underlying health conditions all play a role and are always considered alongside your results.
