A doctor in Taiwan recently shared the shocking case of a 28-year-old woman whose kidney function had deteriorated so severely that it resembled that of an 80-year-old patient.

According to nephrologist Dr. Hong Yongxiang, the woman’s kidney filtration rate had dropped to only:

50 points,

a dangerously low level for someone her age.

Doctors explain that healthy young adults normally have kidney function around:

100 points,

while values below 60 may already indicate kidney failure risk.

What shocked medical staff most was that the woman had:

• no diabetes,
• no high blood pressure,
• no major chronic illness,
• and did not regularly use unusual supplements or medications.

Doctors were initially unable to understand why her kidneys had deteriorated so badly.

After further questioning, the woman finally admitted she had secretly been taking:

diuretic pills

for several years because she wanted to look slimmer before going out or meeting her boyfriend.

According to reports, the woman was slightly overweight and often experienced water retention. Friends had recommended diuretics because the pills could rapidly reduce water weight and make her appear thinner almost immediately.

Doctors explained that a single pill could cause the body to lose:

nearly 3 liters of water,

which could temporarily reduce body weight by around 3 kilograms.

However, repeated long-term dehydration placed enormous stress on the kidneys and gradually damaged their ability to function properly.

Medical experts warn that excessive diuretic use may lead to:

• severe dehydration,
• dangerous electrolyte imbalance,
• abnormal body pH levels,
• kidney damage,
• and even life-threatening complications.

After discovering the cause, doctors immediately ordered the patient to stop using the medication and begin kidney treatment.

Fortunately, after approximately three months of medical care, her kidney function reportedly improved from 50 to around 70 points.

Dr. Hong also warned that some of the most common drug categories associated with kidney damage include:

• diuretics,
• anti-inflammatory painkillers,
• certain antibiotics,
• and contrast agents used in CT scans or heart procedures.

Doctors strongly advise people never to abuse weight-loss medications or use prescription drugs without proper medical supervision, because damage to the kidneys often develops silently and may not show obvious symptoms until it becomes severe.
