Medical experts have cautioned that while proper hydration is essential, excessive water consumption can pose health risks, particularly for individuals with underlying medical conditions affecting fluid balance.
They identified people with kidney disorders, hormonal imbalances, or those on medications influencing fluid regulation as being most vulnerable to overhydration.
According to specialists, the body typically regulates water levels through normal kidney function, but excessive intake within a short time can overwhelm this system.
This may lead to Hyponatraemia, a condition caused by dangerously low sodium levels in the blood, as noted by the Cleveland Clinic. Symptoms can include dizziness, headaches, and in severe cases, altered consciousness.
The warning follows ongoing public discussions about hydration, fueled in part by campaigns from Nigerian health advocate Chinonso Egemba, who promotes regular water intake.
While some critics argue that drinking excessive water may strain the kidneys, experts maintain that adequate hydration actually supports kidney function by aiding the removal of toxins.
A nephrologist, Jacob Awobusuyi, explained that overhydration is uncommon in individuals with healthy kidneys, as excess water is usually excreted through urine.
However, those with impaired kidney function may retain fluid, leading to swelling and complications in severe cases.
Similarly, endocrinologist Olufemi Fasanmade noted that excessive water intake could result in water intoxication, especially among vulnerable groups.
He recommended consuming about 10 to 12 glasses of water daily in hot climates, while monitoring urine colour as a simple indicator of hydration levels.
Despite the risks, experts emphasised that dehydration remains a more common concern, particularly for individuals engaged in strenuous activities or exposed to high temperatures.
