Managing Kidney Health: Concerns About Sports Drinks and Weight Loss

Kidney issues, diabetes, and constitutional problems?

Hello Dr.
Lee, I would like to ask you: 1.
For the past two years, I have been drinking sports drinks mixed with some water from morning till night.
I have developed a habit of drinking sports drinks, and drinking plain water often makes me feel nauseous, leading to insufficient hydration on those days.
I can only dilute the sports drinks with water.
How can I improve this situation? 2.
I also drink about 300cc of sugary sports drinks before bedtime.
Recently, I am very concerned that drinking this before bed might be more harmful to my kidneys or more likely to lead to diabetes compared to drinking it during the day.
3.
Since last year, my weight has suddenly dropped significantly.
I am 172 cm tall, and in just two to three months, my weight decreased from 52 kg to 45 kg, making me feel very weak.
However, my appetite has not decreased, and no matter what I eat, it is difficult to gain weight; I still hover around 45 kg.
Additionally, my sleep schedule is irregular; sometimes I sleep in the morning and sometimes at night.
My gastrointestinal health is not good, as I experience either constipation or diarrhea daily, with very few normal bowel movements.
Could the significant weight loss be related to my daily consumption of sports drinks or my irregular sleep schedule, among other issues? I have visited many medical institutions, but it has been difficult to improve these problems.
I would appreciate any guidance you can provide.
Thank you for your response!

Drinking plain water may cause nausea; it is advisable to consult a gastroenterologist.
Long-term consumption of sugary beverages can increase the risk of developing fatty liver disease, diabetes, and other chronic conditions.
If there has been a significant recent weight loss, it is recommended to see an endocrinologist to check for diabetes or thyroid dysfunction.

Managing kidney health is crucial, especially for athletes and individuals who consume sports drinks regularly. Your concerns about the impact of sports drinks on your kidney function and overall health are valid, and it's important to address them comprehensively.

1. Habitual Consumption of Sports Drinks: Drinking sports drinks throughout the day, even when diluted with water, can lead to excessive intake of sugars and electrolytes. While these drinks are designed to replenish electrolytes lost during intense exercise, they are not necessary for everyday hydration, especially if you're not engaging in prolonged or high-intensity workouts. To improve your hydration habits, consider gradually increasing your intake of plain water. You might try flavored water or herbal teas as alternatives to make hydration more enjoyable without the added sugars and calories. If you find plain water unpalatable, consult a gastroenterologist to explore underlying issues that may be causing your aversion.

2. Consumption Before Bedtime: Drinking sugary sports drinks before bed can indeed pose risks to your kidney health and overall metabolic function. The high sugar content can lead to increased insulin levels and may contribute to insulin resistance over time, raising your risk for type 2 diabetes. Additionally, consuming fluids before bed can disrupt your sleep due to increased urination, which can further affect your overall health. It would be wise to limit or eliminate sugary drinks in the evening and opt for water or herbal teas instead.

3. Significant Weight Loss and Gastrointestinal Issues: The rapid weight loss you experienced, from 52 kg to 45 kg over a short period, is concerning and could be indicative of underlying health issues. Factors such as poor sleep patterns, gastrointestinal disturbances (like constipation and diarrhea), and excessive sugar intake can all contribute to weight loss and malnutrition. It's essential to consult with a healthcare provider, preferably an endocrinologist or a gastroenterologist, to rule out conditions such as hyperthyroidism, diabetes, or gastrointestinal disorders. They may recommend tests to assess your metabolic health and digestive function.

In summary, while sports drinks can be beneficial during intense physical activity, their regular consumption outside of exercise can lead to health complications, including potential kidney strain and metabolic issues. Transitioning to a healthier hydration strategy, monitoring your dietary intake, and addressing any gastrointestinal concerns with a healthcare professional will be crucial steps in managing your health. Additionally, maintaining a balanced diet rich in whole foods, adequate sleep, and regular exercise will support your overall well-being and athletic performance.
