This study was conducted at Ibn Sina Teaching Hospital during the period from (27/1/2024) to (3/7/2024). This study aims to evaluate some physiological variables of renal failure patients undergoing hemodialysis. This study included following up 25 patients with chronic renal failure, and the different variables were compared with the same variables in 25 healthy people (not suffering from any disease). The blood variables were examined during this study, which included a study of the level of hemoglobin concentration, platelets, white and red blood cells, hematocrit, and biochemical variables in the blood serum such as triglycerides and cholesterol. The statistical results showed a significant decrease in all blood variables in renal failure patients compared to the healthy group, except for the number of platelets, which showed a very slight decrease. This decrease indicates the effect of renal failure on kidney function in producing red blood cells and regulating hemoglobin and hematocrit levels. This decrease is one of the main indicators of anemia, which is a common complication of renal failure. The results of biochemical tests showed a decrease in the average level of triglycerides and cholesterol. These results indicate a defect in the metabolism of fats due to renal failure, which increases the risk of heart disease. The current study concluded that there is a negative effect of patients with chronic renal failure in most of the physiological and biochemical variables studied compared to healthy people...............
