Diabetes insipidus (DI) is a rare medical condition that disrupts the body's ability to regulate water, resulting in excessive thirst and an unusually high volume of urine. This condition affects the kidneys' ability to concentrate urine and causes individuals to produce between 3 and 20 quarts of dilute, colourless urine daily, compared to an average of 1 to 2 quarts. It is pertinent to note that DI is not related to diabetes mellitus, which disrupts the body's insulin production.
This condition results from damage to the hypothalamus or pituitary gland, which impairs the production or release of vasopressin, a hormone responsible for water retention. When vasopressin levels are inadequate, the kidneys fail to conserve water, leading to excessive urination. It can result from Brain injuries or surgeries, tumours, infections or inflammation and aneurysms.
Nephrogenic Diabetes Insipidus
This type occurs when the kidneys fail to respond to vasopressin, causing excessive fluid loss. Common triggers include chronic kidney disease, and electrolyte imbalances, such as high calcium or low potassium levels. Additionally, medications like lithium
and urinary tract blockages can also cause Nephrogenic DI.
A rare condition seen only during pregnancy, this occurs when the placenta produces an enzyme that breaks down vasopressin or increases prostaglandin levels, reducing kidney sensitivity to the hormone. Symptoms of this are usually mild and often resolve postpartum but can recur in future pregnancies.
In severe cases, dehydration may develop, manifesting as fatigue, dizziness, dry mouth, confusion, nausea, or fainting. Infants and children with DI may exhibit crankiness, poor feeding, slow growth, fever, or vomiting.
DI stems from issues with vasopressin production or response. Central DI arises from damage to brain structures, while nephrogenic DI relates to kidney dysfunction. Risk factors include:
- Genetic mutations affecting water regulation
- Certain medications like diuretics or lithium
- Metabolic disorders that alter calcium or potassium levels
- Brain injuries or surgeries
Diagnosis And Testing
Diagnosing DI involves a combination of medical history, physical exams, and specialized tests:
- Urinalysis: Evaluates urine concentration and glucose levels to distinguish DI from diabetes mellitus.
- Blood tests: Check electrolyte, glucose, and vasopressin levels.
- Water deprivation test: Measures changes in weight, blood sodium, and urine concentration during fluid restriction.
- MRI: Detects abnormalities in the hypothalamus or pituitary gland.
- Genetic screening: Identifies inherited risk factors.
Although DI is rare, affecting about 1 in 25,000 people, early diagnosis and targeted treatment can significantly improve quality of life. Researchers continue to explore its causes and treatments to better support those living with this challenging condition.

Your weight not only affects your heart health but also your brain health. A recent study published in the Journal of Clinical Endocrinology & Metabolism has revealed a powerful connection between your body weight, heart and brain.
After studying over 500,000 people, scientists discovered that having a high Body Mass Index (BMI) can nearly double your chances of developing brain-related illnesses later in life, which confirms that being overweight and having high blood pressure are not just general health concerns, they are direct causes of dementia.
The study focused heavily on vascular dementia, a specific type of memory loss that occurs when the brain is damaged because of a lack of blood flow.
Think of your blood vessels like a system of pipes. If those pipes are narrowed or blocked due to weight-related issues, the "engine" (your brain) doesn't get the fuel it needs. Over time, this lack of oxygen and nutrients leads to permanent brain damage and the loss of memory and thinking skills.
Researchers found that high blood pressure, often caused by carrying extra weight, is the main "middleman" in this process. Blood pressure is measured with two numbers, and both play a part in brain health:
This is the pressure when your heart beats. It accounts for about 18 percent of the link between obesity and dementia.
This is the pressure when your heart rests between beats. It accounts for about 25 percent of the link. When these numbers stay high, they constantly "batter" the delicate vessels in the brain, causing them to weaken or clog.
Beyond just blood flow, a high BMI impacts the brain in several other ways:
Obesity often causes the body to be in a constant state of "alarm" or inflammation. This can irritate the immune system and eventually damage brain cells.
When the body struggles to process energy and food properly, it changes how the brain uses energy, which can lead to cognitive decline.
A heart that has to work harder to pump blood through a larger body eventually becomes less efficient at sending blood all the way up to the brain. Your heart essentially has to do twice as much work as it would at a lower weight.
The most encouraging takeaway from this study is that dementia isn't always a matter of bad luck or "old age." Researchers call this an unexploited opportunity.
By managing your weight and blood pressure early in life, through a healthy diet, consistent exercise, and good sleep, you are essentially "dementia-proofing" your brain. The researchers suggested that intervening early, possibly even with weight-loss medications before symptoms start, could be a key strategy for protecting brain health in the future.
According to the World Health Organization, one in eight people in the world are living with obesity. In 2022, about 2.5 billion adults were overweight. Causes of it vary, from things like diseases or chronic conditions, to the kind of food that is available to consume.

Heart attacks need immediate intervention and Dr. Balbir revealed one medicine that can save a life when this happens: Aspirin. In an interview with HealthandMe, Dr. Singh revealed that one does not need fancy equipment to help a person having a heart attack.
“If the history of the family history or cholesterol or diabetic. This patient is at risk, so what is the medicine if you get such a symptom? Aspirin.”
Dr. Singh points out that if you or someone near you begins to experience symptoms of a heart attack, such as heavy chest pain, pressure, or unexplained sweating, taking a dissolvable aspirin immediately can be a lifesaver.
By dissolving a tablet (like Dispirin) in a glass of water and drinking it, the medicine dissolves into the bloodstream much more quickly than simply ingesting it.
Aspirin works by thinning the blood and preventing further clotting in the arteries, which can stop a heart attack from getting worse before medical professionals arrive.
Before medical professionals arrive, performing CPR can also help save a person's life; however, one must know the right way to do CPR.
While speaking to HealthandMe, Dr Singh mentioned a viral video where a person collapses and someone attempts to give them CPR while they are still sitting in a chair, notng that this was 'a dangerous mistake' and people should steer clear away from such false videos.
He explained that you cannot perform CPR on someone who is sitting up as the body must be positioned correctly for the heart and lungs to receive the benefit of the chest compressions.
Without the proper technique, blood will not reach the brain and your efforts will not help the patient. Understanding the proper sequence of events is the difference between a failed attempt and a saved life.
If someone collapses, immediately place them flat on their back on a hard floor. You need the ground's resistance to pump the heart manually. In this position, the heart is "sandwiched" between the rib cage and spine. On a soft bed, your presses will fail to squeeze the heart effectively.
Dr. Singh emphasizes that restarting the heart is the absolute priority. Place both hands in the center of the chest and use your body weight to press firmly. By pushing the rib cage toward the spine, you force the heart to pump. Often, once circulation starts, the patient begins breathing again spontaneously.
If the person doesn't wake up, begin a rhythm of three chest presses followed by one mouth-to-mouth breath. Lock your elbows and press hard to ensure the heart is being squeezed between the bones. This specific cycle keeps oxygenated blood moving to the brain, preventing permanent damage during a cardiac emergency.
According to the Centers for Disease Control and Prevention, heart attacks claim a life every 34 seconds. In 2023, it caused nearly 920,000 deaths, one in every three recorded. Hence it is important to know not just the ways to help when someone has a heart attack but also how to prevent them.
