Sodium and potassium are of great importance in the body as they play an important role in controlling the fluid balance in the body and their levels are affected by many factors, the most important of which are nutrition and chronic diseases. This study was designed to determine the extent of variation between the rates of these two elements in adults and the elderly and their importance in the body and their impact on general health, especially in the elderly. We seek to provide results that clarify the relationship between them and contribute to a better understanding of the impact of these elements on the health of the body. This study relied on the statistical aspect, as 82 random samples of different ages and both sexes were collected from different analysis laboratories in the city of Zawiya, with a percentage of (46.3%) males and (53.7%) females. Some percentages should be mentioned in numbers. The results showed that there were no statistically significant differences in the averages of sodium and potassium between males and females in this sample, but indicated that these levels may differ according to age, as the least represented was the group that was less than 20 years old at a percentage of 7.3%. The highest representation is the 30-39 age group at 23.2%, with a greater focus on the middle age groups (30-59 years), which constitute 50% of the sample. According to the statistical analysis, age is the potential factor for variation, whether in the decrease or increase of these two elements. This supports the importance of considering age as a potential factor for variation when studying these two factors. A statistical study shows the extent of variation between the levels of sodium and potassium in adults and the elderly and their impact on general health.........................
