From controlling body temperature and flushing out toxins, adequate hydration plays a vital role in our general health and well-being, water is a life essential. However, while dehydration garners significant attention, overhydration, or drinking excessive amounts of water, is a condition that can have serious and sometimes fatal consequences.
Although it may sound bizarre since drinking water is said to be the solution for most health related problems it is important to recognize how much water is considered "too much" or the risks involved with being overhydrated can maintain a healthy balance.
Water intoxication, also termed hyperhydration, water poisoning or water toxemia, develops when an individual drinks much more water than the kidney can excrete. The main function of the kidneys in the human body is the processing and excretion of excess water. However, the human kidneys can process only up to 0.8 to 1.0 liters of water at a time. Drinking an amount that exceeds this may overwhelm the kidneys and put the electrolyte balance out of sync in the human body.
Electrolytes, especially sodium, are essential in maintaining fluid balance within and outside cells. Hyponatremia is the condition when sodium levels fall below 135 mmol/L, resulting from excessive water intake. This causes water to shift into cells, swelling them. In the brain, this can cause severe complications, including coma or even death.
The symptoms of water intoxication vary from mild to severe. Early symptoms are often similar to dehydration, which makes self-diagnosis challenging. Common symptoms include:
In more serious cases, water intoxication can cause seizures, loss of consciousness, or swelling in the brain. These complications can be fatal if left untreated.
A notable case occurred in 2007 when a woman participating in a water-drinking contest tragically died after consuming nearly two gallons of water in under two hours. More recently, actress Brooke Shields experienced a grand mal seizure attributed to excessive water consumption.
Water intoxication is rare, but certain scenarios can increase the risk:
These endurance athletes are prone to water intoxication, especially if they drink large amounts of water without replacing lost electrolytes. Hyponatremia usually happens during long races or marathons as individuals mistake fatigue and muscle cramps for dehydration and continue drinking water in excess.
Overhydration among military personnel is usually due to severe physical activity in extreme environmental conditions. The total number of hyponatremia cases documented from 2007 through 2022 for the active duty in the United States exceeds 1,600, with a note to this problem on exertion-related overhydration.
Compulsive water drinking, known as psychogenic polydipsia, is linked with some mental illnesses such as schizophrenia and psychosis. People with these conditions tend to drink too much water, causing a hazardous electrolyte imbalance.
Drugs such as MDMA (ecstasy) raise the body temperature and make people thirsty, and at times, some people tend to drink excess water at events like music festivals. MDMA also leads to urine retention, thus exacerbating the dangers of water intoxication.
The exact amount of water that causes intoxication varies from one person to another. However, drinking more than 1 liter of water per hour for several hours raises the risk. For healthy individuals, the risk of overhydration is low unless taking part in extreme physical activity or ignoring thirst cues.
Certain medical conditions, such as kidney or liver disorders, can impair the body's ability to process fluids, and even moderate water intake may be harmful. Similarly, certain medications, such as diuretics and antipsychotics, can affect the perception of thirst or fluid regulation.
The widely touted recommendation of eight 8-ounce glasses of water per day has little basis in fact. According to the National Academy of Medicine, a daily total fluid intake is about 15 cups (3.7 liters) for males and 11 cups (2.7 liters) for females, from beverage sources and from food. Usually, about 20 percent of daily hydration comes from foods such as fruits and vegetables.
A better rule of thumb is to listen to your body and drink water based on thirst. Use the color of your urine as an indicator:
Older adults, whose thirst mechanisms may decline with age, should be proactive about maintaining hydration, especially during illness or hot weather.
The symptoms of water intoxication—such as headaches, fatigue, and muscle weakness—are similar to those of dehydration. If you are unsure which condition you are experiencing, seek medical attention immediately rather than self-treating with more water.
To avoid the dangers of overhydration:
For signs of severe water intoxication-including confusion, drowsiness, seizures, and loss of consciousness-customer is advised to seek medical assistance immediately. In the meanwhile, a salty snack would help to temporarily correct low sodium levels.
Hydration is important to health, but overhydration can be a serious risk; the secret is in finding a balance. Drink enough water to satisfy your body, but not so much that it overwhelms your system. Remember, water is life, but moderation keeps it that way.

Living with someone who has hepatitis can be worrying. People tend to immediately wonder whether they are at risk simply by sharing meals, hugging, or living under the same roof.
Fortunately, the answer depends on the type of hepatitis, and in most cases, everyday household contact does not spread the virus.
Dr. Shalimar, Prof. Department of Gastroenterology, AIIMS explains, "Hepatitis means inflammation of the liver. There can be many causes, but viral hepatitis is one of the most common. There are different hepatitis viruses, including A, B, C, D, and E. Some cause acute illness, while others can lead to long-term liver damage, including cirrhosis and liver cancer."
Experts say misinformation surrounding hepatitis often leads to unnecessary fear and stigma, causing patients to feel isolated. Understanding how different hepatitis viruses spread can help families protect themselves without avoiding normal interactions.
Dr Nanda Kishore M, Gastroenterology, Athulya Geriatric Care Hospital, answers our question, "No, Hepatitis is not a communicable disease that spreads through everyday contact such as hugging, holding hands, coughing, or sneezing."
For most forms of hepatitis, the answer is no. However, hepatitis B is spread through contact with infected blood and certain body fluids. Household transmission is possible, but it generally occurs when infected blood enters another person's bloodstream.
Possible household risks include sharing:

Dr. Kishore says that the mode of transmission largely depends on the type of hepatitis infected.
He says, "Hepatitis A and E are predominantly spread via means of contaminated food and water, while Hepatitis B and C are transmitted through infected blood and certain bodily fluids."
Hepatitis B is preventable by vaccine. Household members of someone with chronic hepatitis B are usually advised to get tested and vaccinated if they are not already immune.
Dr. Shalimar says, "For hepatitis B, current treatment controls the infection, and newer therapies under development offer hope for a functional cure in the future. Vaccination has dramatically reduced hepatitis B in many parts of the world. Expanding vaccination coverage remains one of the most effective ways to prevent the disease."
Living with a hepatitis infected individual is generally safe given that basic hygiene and recommended precautions are followed strictly. Understanding these facts helps reduce unnecessary fear and stigma associated with it.

Living with someone who has hepatitis does not mean you need to keep your distance. Instead, focus on practical precautions:
Dr. Ankur Jain, Associate Director & Unit Head, Gastroenterology, Hepatology & Endoscopy, Max Hospital, Dwarka, explains, "Hepatitis B and Hepatitis C continue to affect millions of people worldwide and remain major causes of liver cirrhosis and liver cancer. Individuals with a history of blood transfusions before routine screening, unsafe injections, or other risk factors should discuss screening with their physician.
He adds, "The liver has an extraordinary capacity to heal, but only if we identify problems early and address the underlying causes. Prevention, timely screening, and simple lifestyle modifications remain our most powerful tools in reducing the growing burden of liver disease in India."

Hepatitis remains one of the most misunderstood liver conditions, largely because it isn't a single disease but a group of infections—A, B, C, D, and E—each of which behaves very differently once it enters the body.
The question "can hepatitis be cured?" doesn't have one straightforward answer. The truth lies somewhere between full recovery and lifelong management, depending entirely on which type of hepatitis a person has contracted.
Hepatitis A and E are generally short-lived infections. The liver, in most cases, clears these viruses naturally without any specific antiviral medication. Rest, hydration, a balanced diet, and avoiding alcohol are usually enough to help the body recover fully. Chronic infection is rare with these two types, and when it does occur, particularly with Hepatitis E in people with weakened immunity, it can still be treated successfully.
Hepatitis C tells a much more encouraging story. Thanks to advances in medicine, Direct-Acting Antivirals, or DAAs, now cure more than 95 percent of cases. These are oral tablets taken for roughly eight to twelve weeks, and they carry minimal side effects compared to older treatments. For patients diagnosed early, Hepatitis C is, quite genuinely, curable.
Hepatitis B and D are a different story altogether. When the infection is acute, the body often fights it off on its own without much trouble.
Chronic cases, though, are far tougher to deal with. As of now, no medication can fully remove the Hepatitis B virus from the body once it settles in. What doctors can do is keep it under control, usually through antiviral tablets or interferon injections, so that it doesn't quietly damage the liver over time and lead to cirrhosis or cancer. For many patients, this isn't a short course of treatment. It's something they may need to stay on for years, and in several cases, for the rest of their lives.
Hepatitis D is considered the more severe of the two, and it only shows up in people who already have Hepatitis B; it cannot infect someone on its own. Treatment choices here are still quite limited. A few newer drugs have shown some promise in keeping the disease in check, but nothing yet counts as an actual cure. When the liver damage has progressed too far, a transplant sometimes becomes the only way forward.
The single most important factor in determining outcomes across all types of hepatitis is timing. Detected early, Hepatitis C can be eliminated. Detected early, Hepatitis B can be controlled well enough that liver damage never progresses. Left unchecked, however, both can silently damage liver tissue for years before symptoms even appear.
Regular liver function tests, hepatitis screening for those at risk, and vaccination—especially for Hepatitis B—remain the strongest tools available for prevention and timely intervention.
Hepatitis doesn't follow a single script, and that's something patients often find confusing at first. Some forms clear up completely with the right treatment, others require ongoing management to keep the virus in check, and in many cases, vaccination and timely screening make the real difference in avoiding complications down the line.
Knowing exactly which type of hepatitis one is dealing with is what allows a doctor and patient to set realistic expectations and work out a treatment plan that actually fits the situation.

The rise of GLP-1 medications such as Ozempic (semaglutide), Wegovy, Mounjaro, and Zepbound (tirzepatide) has transformed obesity and diabetes treatment.
However, soaring demand and earlier drug shortages also fueled the rapid growth of compounded GLP-1 drugs, which are now under increasing scrutiny from regulators and medical experts.
Over the past few months, the U.S. Food and Drug Administration (FDA) has intensified its crackdown on compounded GLP-1 products, warning that patients could face quality, dosing, and safety concerns if they obtain these medications from unlawful sources.
A compounded drug is a medication that is custom-made by a licensed compounding pharmacy to meet an individual patient's specific medical needs. For example, removing an allergen, changing the dosage, or preparing a formulation that is not commercially available.
The FDA said, "Compounded drugs are not FDA-approved, which means the agency does not review them for safety, effectiveness or quality before they are marketed."

Demand for GLP-1 medications for weight loss skyrocketed worldwide between 2022 and 2025, leading to shortages of semaglutide and tirzepatide.
During these shortages, compounding pharmacies were legally allowed under specific circumstances to prepare several versions of these medications.
Many patients turned to compounded GLP-1s because they were often affordable, available, and easier to buy online.

FDA's efforts to restrict this practice include widespread compounding of semaglutide, tirzepatide, and liraglutide.
The agency has proposed excluding these drugs from the list of bulk substances used for large-scale compounding because FDA-approved alternatives are now available.
It has also issued warning letters to companies producing compounded GLP-1 products outside permitted circumstances.

A new University of Colorado Anschutz Medical Campus secret shopper study published in July 2026 found that the compounded GLP-1 market remains active even after shortages have been curbed.
Researchers reported that many online pharmacies were still selling compounded semaglutide or tirzepatide, with some products originating from pharmacies lacking compounding licenses.
Small differences in concentration may result in patients receiving too much or too little medication.
Injectable medicines must be manufactured under strict sterile conditions. Improper preparation increases the risk of contamination.
Some compounded products have reportedly used semaglutide salts or added vitamins and other substances that are not present in FDA-approved versions. The FDA has previously stated that certain semaglutide salt forms have not been demonstrated to be safe or effective.
Because compounded products are not FDA-approved, they have not undergone the rigorous clinical trials evaluating effectiveness, manufacturing consistency, and long-term safety.
Experts warn that some websites advertise compounded GLP-1 medications that may not come from legitimate pharmacies at all.
