Office workers drink 2 liters of water a day but still have kidney stones. Doctors point out 4 “mistakes” to remember by heart.
Office workers drink 2 liters of water a day, wondering why they still have kidney stones. Doctors point out 4 “mistakes” to remember by heart. Drinking the wrong way, drinking a lot doesn’t help.

There was an office worker who regularly drank no less than 2 liters of water a day. However, not long ago, he felt severe pain in his waist, so he rushed to see a doctor and found out that he had kidney stones. This surprised him because he thought that drinking a lot of water would not cause kidney stones. The doctor came out to clear up the misunderstanding that “drinking a lot of water does not mean that you will not have kidney stones.”
Taiwanese urologist Dr. Chu Yuan-jung shared the โปรโมชั่นพิเศษจาก UFABET สมัครตอนนี้ รับโบนัสทันที case on his personal Facebook page, saying that a 35-year-old office worker had severe back pain that made him sweat and unable to stand. When it was discovered that he had a 5-millimeter kidney stone, he drank more than 2 liters of water every day.
Why do I still get kidney stones even though I drink a lot of water?
Clinical studies have shown that more than 70% of kidney stone patients drink a significant amount of water each day. However, the key factor is “how to drink water”, not just the total amount. Because if you drink a lot of water at a time, the body will excrete it quickly, causing the urine to be diluted for only a short period of time before becoming concentrated again, which does not help prevent kidney stones. The key is to “drink water regularly and in a rhythm” rather than just measuring the total amount.
4 ways to drink water effectively to prevent kidney stones
1. Drink little and often. Sip slowly.
- Suitable water volume: body weight (kg) × 30 ml.
- If you exercise a lot, sweat a lot, or stay in an air-conditioned room for a long time, increase to × 40 ml.
- Don’t wait until you’re thirsty to drink water. It’s recommended to sip 200–300 ml every 30–60 minutes to keep your kidneys working.
2. Don’t wait until you’re thirsty and don’t drink a lot at once.
- Thirst indicates that the body has been dehydrated for 2–3 hours.
- If you drink a lot at once, your body will only absorb about 200 ml in 20 minutes. The excess will be excreted immediately.
- Therefore, the water you drink cannot really enter your cells or dilute your urine.
- Therefore, you should sip it slowly and in small amounts so that your body can fully absorb it.
3. Observe the frequency of urination.
- Adults should generally urinate 4–7 times a day, or every 2–3 hours.
- If you pass water less than 4 times a day, you are drinking too little water and your urine is concentrated.
- Which increases the risk of developing kidney stones.
4. Tea, coffee and sweetened beverages are not as good as plain water.
- Beverages such as milk tea, coffee, soft drinks, or sweetened beverages are not considered water that helps hydrate the body.
- This is because the caffeine and sugar in these drinks interfere with calcium absorption and increase calcium concentration in the urine.
- Therefore, it increases the risk of kidney stones.
- The recommendation is that every time you drink these drinks, you should drink another 300 ml of plain water to help replace the lost water and help your kidneys work well.
