Effect of fasting on various biochemical constituents of blood

ABSTRACT

Thirty healthy volunteers [15 males and 15 females] in the age group 25-45 years were studied for the changes in a group of selected biochemical entities of blood during the month of Ramadan [fasting month of Muslims]. Results showed a non significant reduction in blood sugar, serum total cholesterol and total lipid levels. Serum electrolytes [Na[+], K[+], Cl[+]] remained almost unaffected. An increase in the level of Hb., urea, creatinine, uric acid, serum proteins and triglyceride has been observed in about 80% subjects and can be attributed to the haemoconcentration associated with reduced fluid intake during Ramadan and the change in pattern and frequency of eating
