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.

What Is Water Intoxication?

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.

Symptoms of Water Intoxication

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:

• Headaches
• Nausea and vomiting
• Muscle cramps or weakness
• Fatigue or drowsiness
• Confusion and disorientation

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.

Causes of Water Intoxication

Water intoxication is rare, but certain scenarios can increase the risk:

1. Sporting Events and Endurance Training

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.

2. Military Training

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.

3. Mental Health Conditions

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.

4. Drug Abuse

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.

How Much Water Is Too Much?

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.

How Much Water Is Enough?

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:

• Light yellow urine indicates proper hydration.
• Dark yellow urine may indicate dehydration.

Older adults, whose thirst mechanisms may decline with age, should be proactive about maintaining hydration, especially during illness or hot weather.

Water Intoxication vs. Dehydration

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.

Preventing Water Intoxication

To avoid the dangers of overhydration:

• Drink water gradually throughout the day rather than consuming large amounts at once.
• Replace lost electrolytes post high-intensity exercise or heavy sweating.
• Consider using sports drinks or salty snacks to help replenish sodium.
• Keep track of fluid consumption during long-duration activities, and do not consume more water than the body is losing in terms of electrolytes.
• If on medications or have specific medical conditions, check with your doctor regarding the safety of drinking water.

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.

From upscale salons to local aesthetic clinics, a quick IV infusion of glutathione is being offered for skin brightening and anti-ageing. But these increasingly popular cosmetic drips may neither be legal nor safe and may carry several health risks, doctors have warned.

Glutathione is an unapproved therapy that involves risks at many levels, including toxins. As per the US FDA, injectable/IV glutathione is not FDA-approved as a safe compounded sterile injectable, carrying high risks of contamination and severe adverse reactions.

Warning Against Glutathione IV Drips

In a social media post on X, noted hepatologist Dr Cyriac Abby Philips called out an advertisement for a clinic offering glutathione IV drips, promising skin whitening.

He warned people to “absolutely” avoid it, as the effects on skin may be temporary but carry long-term health risks from kidney to liver dysfunction, and potentially fatal skin reactions.

“Because the body continuously produces melanin, any potential lightening effect is temporary. Once the extreme systemic doses are stopped, the skin's natural pigmentation returns,” Dr Abby said.

Further, he also stated that the procedure is mostly offered by "cosmetologists" or commercialized dermatology clinic chains. As cosmetology is not a recognized medical degree or a protected medical title under the National Medical Commission in India, people claiming to be "cosmetologist" is not really a medical practitioner, but merely certified "coaches" or "wellness experts".

Poor Evidence Supporting IV Glutathione

The expert, better known as “LiverDoc” also noted that the clinical evidence supporting IV glutathione is exceptionally poor.

“The administration of IV glutathione in dermatology and cosmetology clinics is a lucrative marketing trend that operates outside the bounds of evidence-based medicine”.

“Marketing claims rely heavily on anecdotal reports and a single, widely criticized trial that suffered from a tiny sample size, poor study design, and unreliable evaluations,” he added.

FDA Warning Over Glutathione IV Treatments

“Because IV glutathione is not approved for cosmetic use, the solutions utilized in wellness clinics and med-spas are typically sourced from "compounding pharmacies". This bypasses standard pharmaceutical manufacturing regulations, introducing severe risks”.

Dr. Abby explained that a "compounded drug" is a custom medication created by a pharmacist or physician who combines, mixes, or alters ingredients on their own.

He cited how in August 2026, the US FDA issued an urgent safety warning after dozens of patients experienced potentially fatal infection (sepsis)-like symptoms — including fever, chills, low blood pressure, and hospitalization — following glutathione IV treatments.

“Clinics were found to be compounding IV drips using dietary-supplement-grade powder, which contained dangerously high levels of bacterial endotoxins. Administering high doses has been linked to severe adverse effects, including anaphylaxis, acute kidney and liver dysfunction, and potentially fatal skin reactions like Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS and TEN),” Dr Abby said.

India Tightens Rules Around Injectable Cosmetics

In May 2026, the Central Drugs Standard Control Organisation (CDSCO) tightened rules around cosmetic use.

In a new public notice issued, the CDSCO stated that cosmetic products that come in injectable form do not fall under the definition of cosmetics under the law. It said that such products are not permitted for use by consumers, professionals, or aesthetic clinics.

Other Potential Health Risks

According to the Philippines FDA, given that glutathione affects the production of melanin — the pigment that gives human skin, hair and eyes their colour — there are theoretical concerns about the long-term skin cancer risk.

Other potential risks include transmission of infectious agents, such as HIV, hepatitis C and B. This is of particular concern when a non-medical practitioner administers this treatment or it is done in a non-sterile facility.

According to the World Health Organization (WHO), hernia repair is one of the most important surgical procedures, with published estimates suggesting that around 20 million hernia repairs are performed each year globally. For most patients, recovery is smooth, steady, and uncomplicated. It is one of the most performed surgeries globally, and for most patients, recovery is steady. Mild pain, swelling, and discomfort during the first few weeks are usually part of the healing process and improve with time. However, when a wound refuses to heal, pain continues to worsen, or there is persistent discharge from the surgical site, these symptoms should never be ignored.

Although complications following hernia mesh repair are uncommon, delayed recognition can make treatment far more challenging. One of the more serious complications occurs when the surgical mesh erodes into surrounding organs, particularly the intestine, leading to infection, chronic wounds and, in rare cases, an entero-cutaneous fistula, an abnormal connection between the bowel and the skin.

A recent patient cases highlights why early medical attention is so important. An umbilical hernia surgery performed years ago led to complications for a 32-year-old lady from Bengaluru. What was supposed to be a simple procedure turned out to be a prolonged medical ordeal for the patient. The injury could not be healed completely, and as time went by, the patient developed persistent drainage from the injury site, which made her daily tasks increasingly difficult.

A further assessment revealed that the mesh had eroded into the bowel and caused an entero-cutaneous fistula. At this point, the surgery was going to be much more complicated than a regular hernia repair. This is a particularly challenging case for surgeons, requiring very detailed planning, since there is always a high probability of finding dense scar tissue and adhesions, which made it impossible to properly detach the bowels.

The surgery was done as a complicated laparoscopic revision operation, during which the adhesions were freed; both meshes were removed, and the part of the bowel that was affected by them was recovered, and the abdominal wall structure was restored. The postoperative period went quite well, and the man was relieved of all the discharge, and his intestinal function was restored within a few weeks.

Such cases may be quite rare, but they send a clear message – never neglect prolonged symptoms, thinking that they are just a part of the recovery process. Hernias are easily repaired, but if healing goes slowly, it is always better to do additional tests to avoid complications.

Signs that might arouse concern about the patient’s condition after the hernia surgery:

1. The wound is not healing properly while waiting for the healing process.

2. The wound is continuously oozing secretions.

3. An unexpected increase in pain in contradiction to the healing phase.

4. Body temperature is above normal or other symptoms of infection are present.

5. An unexpected formation or swelling has appeared in the surgical area.

It should also be mentioned that not everyone suffering from pain after the operation faces a serious complication. However, those with ongoing or worsening health conditions should not perform self-treatment and wait for the issues to resolve.

Advances in minimally invasive laparoscopic surgery have made it possible to successfully manage many complex hernia mesh complications while reducing pain, hospital stay, and recovery time. At the same time, successful treatment depends not only on surgical expertise but also on timely diagnosis and appropriate follow-up.

The goal is not to create anxiety around hernia surgery. Mesh repair remains a safe and effective treatment for most patients. The key message is simple: listen to your body. If your recovery process takes much longer than expected, or there is something that appears abnormal, you should consult with a doctor right away. There are instances where timely action prevents complications and allows for a full recovery.

A globally introduced, newer-generation cataract lens was used in India for the first time, enhancing patient’s recovery journey and treatment outcome

Since her diabetes diagnosis 5 months ago, Mrs Vani Vaish had done what doctors tell every diabetic to do - turn up regularly for an eye exam because diabetes can quietly damage the blood vessels and nerves in your eyes. The eye damage often gives no major noticeable warning until real damage has been done, which is exactly why the screening isn't optional, symptoms or not.

How A Routine Eye Check-Up Revealed A Cataract

During one of these routine visits, Mrs Ahuja complained of blurring in her vision and increasing glare around headlights and streetlamps at night. Her ophthalmologist identified a cataract. For people living with diabetes, regular eye examinations can be important for more than monitoring diabetic retinopathy, as diabetes can also increase the risk of developing cataracts and may lead to their occurrence at a younger age.

The treatment options were discussed with her in detail, including the potential benefits and limitations of the technology, individual variations in outcomes and the considerations involved in selecting a presbyopia-correcting lens. Following a detailed evaluation, Mrs Ahuja underwent cataract surgery with implantation of the Clareon PanOptix Pro, a newer-generation trifocal intraocular lens that had recently become available in India.

What The Newer-Generation Lens Is Designed To Do

The significance of the technology lies in what it is designed to change in cataract vision correction. Trifocal lenses split incoming light to provide vision across near, intermediate and distance ranges. The newer-generation optical design used in PanOptix Pro is intended to use available light more efficiently and reduce light scatter — an advancement that aims to support better quality of vision across different distances while addressing some of the visual compromises associated with multifocal lens technology.

Because no two patients have the same visual demands, expanding access to newer technologies plays a critical role in modern care. Our role is to evaluate each patient’s unique needs and ensure that the most suitable and advanced treatments available actually reach the patient, giving them every opportunity for a better quality of life.

The procedure marked the first use in India of the globally introduced Clareon PanOptix Pro lens. For MRs Vaish, the outcome of the treatment has matched what she hoped for. She reports clear vision and no floaters or other visual disturbances. Her recovery has also been smooth, and she has not even needed the temporary protective glasses in the days following the procedure.

Why Regular Eye Exams Matter For People With Diabetes

Her case highlights two important aspects of modern eye care. Regular eye examinations are important especially for people living with diabetes. A routine screening intended to monitor retinal health can also help identify other conditions affecting vision, including cataracts.

It also demonstrates that access to advanced medical technologies can significantly expand treatment possibilities and enhance the patient's recovery journey. When newer innovations are combined with careful clinical evaluation and personalised decision-making, they can help doctors move beyond a one-size-fits-all approach to treatment and offer patients options better suited to their individual visual needs and lifestyles.
