The objective of this study was to correlate body weight and urine pH. The classification of urine as it is dilute acidic or basic solution known as urine pH. Neutral pH of urine is seven. If the solution pH is less than seven, then it is acidic. If the pH of the solution is greater than seven, then it is basic. When the concentration of sodium ions is more, greater the acidity of the urine solution. Alkaline urine contains bicarbonates-carbonic acid buffer. Acidosis, diarrhea, dehydration and starvation is faced when the pH is acidic. Normal body weight is necessary for a proper heath. If there is a high level of cholesterol leads to many disease, like cardiac diseases and many more. Subjects took urine sample in a container and then dipstick test was performed. We dipped the stick for 2-3 seconds and then allow to change the color of the stick. After that, we compared the color variation with the standard and then noted the values for the urine pH. We took the urine sample of the patients and meanwhile we measured the weight of the patients. We analyzed the results by estimating the percentages. In this project, it was a questionnaire based study in which we asked the patients about their pH in urine. of the samples. There were four different categories of body weights and also noted the readings accordingly. It was concluded that human body weight and urine pH had a significant relationship.
