Is It Bad For You To Drink Too Much Water – Drinking too much water can cause complications, doctors say lead to low sodium levels or brain swelling. The usual daily intake should be eight to 10 cups; Too much water can lead to water intoxication
With mercury levels soaring, doctors stress that staying hydrated is essential, but too much may not be the best course of action to take.
Is It Bad For You To Drink Too Much Water
Doctors said recent research has indicated that excessive fluid intake or excess fluid buildup can lead to dangerously low levels of sodium in the blood or cause brain swelling, especially among the elderly.
Can You Drink Too Much Water? 4 Signs To Look After
K. K. Aggarwal, the immediate past president of the Indian Medical Association (IMA), said, “Excessive water can lead to what is known as water intoxication. In this condition, the amount of salt and other electrolytes in the body becomes too dilute.”
“A person who drinks a normal amount of water is straw-colored to a translucent yellow color. Although most people think that clear urine is the healthiest sign of hydration, urine with no pigmentation at all may be an indication that you are drinking a lot of water.”
This varies depending on the individual’s height, weight, and exercise patterns. Drinking too much water or not having an effective mechanism to remove it from the body can cause water levels to build up. This, in turn, dilutes important substances in the blood. Endurance athletes, such as those who run marathons and races Triathlon, they sometimes drink a lot of water before and during the event,” he said.
Some common symptoms of dehydration include nausea, vomiting, headache, and changes in mental status such as confusion or disorientation. Left untreated, it can lead to muscle weakness, spasms or cramps, seizures, loss of consciousness, and coma.
Is It Possible To Drink Too Much Water?
Hyponatremia occurs when the concentration of sodium in the blood is abnormally low. Sodium is an electrolyte and helps regulate the amount of water in and around cells. When one drinks a lot of water, it simultaneously causes the water levels in the body to rise and the cells begin to swell. This swelling can cause many health problems from mild to life-threatening.
“Some other conditions that can cause hyponatremia include certain medications, problems with the heart, kidneys, or liver. Chronic diarrhea and hormonal changes. It is important to track down the cause and take adequate precautions to prevent overhydration, otherwise the condition can lead to serious health problems,” Dr. Agarwal said. become critical.”
The daily intake of water should be spaced out, said Jitendra Kumar, Director of the Nephrology and Kidney Transplant Unit, at QRG Health City.
Don’t drink too much water immediately after eating because it hinders digestion by increasing intestinal pressure and diluting digestive enzymes. If water is taken in large quantities continuously, it may lead to kidney stones and chronic kidney disease.”

He added that sudden dehydration could lead to acute kidney failure and loss of consciousness. People with kidney or heart failure are usually unable to tolerate excessive fluid intake. In such circumstances, fluid intake should be restricted as per the advice of the physician.
Gaurav Jain, Senior Consultant, Internal Medicine, Dharamshila Narayana Super Specialty Hospital said, “It is true that drinking too much water can also cause complications. You have to understand your body’s water requirements. One liter of water per 15 kg of body weight is the requirement. actual body water.
“To meet the water needs of the body, it is necessary to consume 50% of plain water and 50% in the form of other water sources such as fruits, milk, vegetables, etc., which also supplement the level of electrolytes in the body. Consuming a lot of water can dilute the existing sodium and potassium. In the body, it is known as a dilute hyponatremia. Not only that, but excess water can also lead to complications in someone with weak heart and kidneys.” O is an indispensable condition of life. Water makes up about 66 percent of the human body, and it runs through the blood, inhabits cells, and lurks in the spaces in between. Every moment water escapes from the body through perspiration, urination, defecation or exhalation, among other methods. It is essential to replace these lost stores but rehydration can be overdone. There is such a thing as a fatal water overdose.
Earlier this year, a 28-year-old California woman died after participating in a radio station’s live water drinking contest. After downing about six liters of water in three hours in a “Hold Your Wee for a Wii” (Nintendo game console) contest, Jennifer Strange vomited, came home with intermittent headaches, and died of so-called water intoxication.
Signs You’re Drinking Too Much Water
There are many other tragic examples of death by water. In 2005, a fraternity at California State University, Chico, left a 21-year-old man for dead after he was forced to drink large amounts of water between push-ups in a cold basement. Clubgoers taking MDMA (“high”) died after drinking copious amounts of water trying to rehydrate after long nights of dancing and sweating. Excessive attempts to hydrate is also common among endurance athletes. Study 2005 in
Hyponatremia, a word combined from Latin and Greek roots, translates as “lack of salt in the blood.” In quantitative terms, this means a blood sodium concentration of less than 135 mmol per liter, or approximately 0.4 ounces per gallon, and a normal concentration is somewhere between 135 and 145 mmol per liter. Severe cases of hyponatremia can lead to water intoxication, a disease whose symptoms include headache, fatigue, nausea, vomiting, frequent urination, and mental confusion.
In humans, the kidneys control the amount of water, salts, and other solutes that leave the body by sifting the blood through millions of convoluted tubes. When a person drinks a lot of water in a short period of time, the kidneys cannot expel it fast enough and the blood becomes waterlogged. The excess water is attracted to areas where the concentration of salt and other dissolved substances is higher, so the excess water exits the blood and eventually enters the cells, which inflate like balloons to absorb it.
Most cells have room to stretch because they are embedded in elastic tissues such as fat and muscle, but this is not the case for nerve cells. Wolfgang Liedtke, a clinical neuroscientist at Duke University Medical Center, explains that brain cells are tightly packed inside a rigid bony cage, the skull, and they have to share that space with blood and cerebrospinal fluid. “Inside the skull there is almost no room for expansion and bulging,” he says.

Thus, brain edema, or swelling, can be disastrous. Amin Arnaout, Chief of Nephrology at Massachusetts General Hospital and Harvard Medical School, explains: “Rapid and severe hyponatremia causes water to enter the brain cells resulting in brain swelling, which manifests as seizures, coma, respiratory arrest, and brainstem herniation.” , and death.” school.
Where did people get the idea that drinking massive amounts of water is healthy? A few years ago, Heinz Valtin, a kidney specialist at Dartmouth Medical College, decided to determine whether the popular advice to drink eight eight-ounce glasses of water a day could stand up to scientific scrutiny. After digging through the peer-reviewed literature, Valtin concluded that there were no scientific studies to support the adage “eight x eight” (for healthy adults who live in temperate climates and get light exercise). In fact, drinking this much or more “can be harmful, both in precipitating dangerous hyponatremia and exposure to pollutants, and also in causing many people to feel guilty for not drinking enough,” he wrote in his 2002 review of
. Since his findings were published, Valtin says, “not a single scientific report published in a peer-reviewed publication has proven otherwise.”
Most cases of water poisoning aren’t simply caused by drinking too much water, says Joseph Verbalis, MD, chief of medicine at Georgetown University Medical Center. It’s usually a combination of excessive fluid intake and increased vascular secretion (also called antidiuretic hormone), he explains. Vasopressin is produced by the hypothalamus and secreted into the bloodstream by the posterior pituitary gland. Vasopressin instructs the kidneys to conserve water. Its secretion increases during periods of physical stress — during a marathon, for example — and may cause the body to conserve water even if a person drinks large amounts.

Every hour, a healthy kidney at rest can excrete 800 to 1,000 milliliters, or 0.21 to 0.26 gallons, of water, so a person can drink water at a rate of 800 to 1,000 milliliters per hour without experiencing a net gain in water, Verbalis explains. However, if that same person was running a marathon, the stress of the situation would increase vasopressin levels, reducing the excretion capacity of the kidneys to 100 milliliters per hour. He says that drinking 800 to 1,000 milliliters of water per hour under these conditions can lead to a net excess of water, even with heavy sweating.
While exercising, “you have to balance what you drink with what you sweat,” and that includes sports drinks, which can also cause hyponatremia when consumed in excess, Verbalis advises. “If you’re sweating 500ml an hour, that’s what you should be drinking.”
But measuring sweat secretion is not easy. How does a marathon runner, or anyone, decide how much water to consume? As long as you’re healthy and equipped with a thirst meter unaffected by aging or mind-altering drugs, follow Verbalis’ advice, “Drink until
