Stress is an unavoidable part of life, and while it often carries a negative connotation, it is actually a fundamental survival mechanism. When faced with a perceived threat, whether physical or emotional, the body instinctively reacts to protect itself. This automatic response is commonly known as the "fight, flight, or freeze" response. While it serves an essential function in dangerous situations, chronic activation of this response due to daily stressors can have significant consequences for mental and physical health.
The body’s response to stress is rooted in human evolution. When our ancestors encountered a predator, their nervous systems immediately prepared them to either confront the threat (fight), escape to safety (flight), or become still and unnoticed (freeze). While modern-day stressors may not include wild animals, our nervous system reacts similarly to job pressures, financial worries, or social conflicts.
According to the Cleveland Clinic, stress is the body's response to change, activating a physiological reaction that helps us adapt and protect ourselves. While short-term stress can be beneficial, prolonged exposure can lead to an overactive stress response, negatively impacting overall well-being.
The fight response prepares the body for direct action. When triggered, the nervous system releases adrenaline, increasing heart rate, blood pressure, and muscle tension. While this reaction once helped early humans fend off predators, today it manifests as irritability, frustration, or aggression.
For instance, the employee who has experienced too much workload may work extremely long hours just to succeed. In short term, the action may produce good results but mostly ends in burnout, anxiety, and physical illness, for example, tension headache or digestion problems.
The flight response triggers an intense need to remove oneself from a stressful situation. Just as our ancestors would flee from danger, modern individuals may avoid conflict, quit jobs impulsively, or detach from relationships when overwhelmed.
Flight mode is linked with restlessness and anxiety. Individuals may have a sense of needing to get up and go-pacing, changing environments constantly, or avoiding tasks that seem too overwhelming. Someone with a flight response might have the desire to change jobs constantly, relocate constantly, or become reclusive in order to avoid perceived dangers.
The freeze response occurs when the nervous system perceives a threat as too overwhelming to fight or flee. Rather than taking action, individuals shut down, feeling numb, disconnected, or paralyzed by fear.
Unlike fight or flight, which involve heightened activation, freeze mode slows down physiological functions. A person experiencing freeze mode may feel physically unable to move, struggle to make decisions, or find themselves dissociating from their emotions. This can manifest in situations such as public speaking anxiety, where someone might "blank out" or feel stuck in the moment.
When faced with a stressor, the autonomic nervous system (ANS) activates, triggering physiological changes, including:
For those experiencing the freeze response, the body undergoes a different reaction, often reducing heart rate and causing physical immobility rather than heightened activation.
While the stress response is necessary for survival, frequent activation due to daily stressors can take a toll on health. Recognizing your default response—whether fight, flight, or freeze—can help in developing effective coping mechanisms.
If possible, changing your environment can help signal to your brain that the threat has passed. Stepping outside for fresh air, finding a quiet place, or distancing yourself from overwhelming stimuli can help regulate emotions.
Deep, slow breathing can be used to counteract the stress response by engaging the parasympathetic nervous system, which promotes relaxation. Techniques such as diaphragmatic breathing or the 4-7-8 method (inhale for four seconds, hold for seven, exhale for eight) can be particularly effective in calming the body.
This helps release pent-up energy and aids in the endorphin cascade, natural boosters for our mood.
Relieving oneself from stress can come in many ways, but sharing it with trusted friends, a family member, or a good therapist will sure give that psychological boost of hope. Social support is an especially effective way of cushioning people against the stressors that they are subjected to in chronic forms.
While occasional stress is normal, chronic activation of the fight, flight, or freeze response can indicate underlying mental health concerns, such as anxiety disorders or post-traumatic stress disorder (PTSD). If stress is affecting daily life—leading to sleep disturbances, difficulty concentrating, or persistent feelings of fear—it may be time to consult a mental health professional.

AIIMS New Delhi has successfully performed its second dual kidney transplant using organs from a marginal donor. The procedure highlighted a strategy that could help make greater use of kidneys that may otherwise be rejected for transplantation.
The procedure was carried out on July 28 by a multidisciplinary team from the Departments of Surgical Disciplines, Nephrology, Anaesthesia, Transplant Immunology and the Organ Retrieval Banking Organisation (ORBO).
The donor was a 70-year-old woman from Command Hospital, Chandimandir, Chandigarh. Because of her advanced age and the marginal characteristics of the donated kidneys, doctors transplanted both kidneys into a single 56-year-old woman.
The organs were transported from Chandigarh to New Delhi by an Army helicopter. According to AIIMS, despite a cold ischaemia time of 12 hours, both kidneys were functioning immediately after transplantation.
The recipient showed no complications after the transplantation and was discharged after 10 days with normal kidney function.
In a conventional kidney transplant, one donated kidney is transplanted into a recipient. Meanwhile, in a dual kidney transplant both kidneys are placed into one patient from the same deceased donor.
The approach is considered when the donor is older or the kidneys have characteristics that suggest that a single kidney may not provide sufficient function.
In simple terms, two kidneys that have lower individual functional capacity may be able to provide adequate overall kidney function when transplanted together.
Research has previously found that dual kidney transplantation can be a viable option for kidneys from older or marginal donors. Transplant teams carefully assess the donor organs and recipient before deciding whether using both kidneys together could provide adequate renal function.
A 2025 analysis comparing single and dual transplantation from marginal donors also highlighted the potential of using kidneys from a deceased donor.

The milestone comes as India faces shortage of transplantable organs. India recorded 20,138 organ transplants in 2025, crossing the 20,000 mark for the first time, but the number of patients needing transplants remains far higher than the available organs.
Recent reports has also highlight the country's mounting transplant needs that still remain unmet despite its position as one of the world's largest transplant centres by volume.
This makes the ability to safely use organs from older or marginal donors particularly important.
“Dual kidney transplantation from carefully selected marginal donors represents an important strategy for increasing the utilization of deceased-donor organs,” AIIMS said in the press release.
AIIMS said the successful transplant demonstrates its efforts to “maximize the utilization of marginal donor organs” and help patients with end-stage kidney disease receive organs at the earliest.

The immediate functioning of both kidneys despite around 12 hours of cold storage is certainly encouraging. However, the patient’s discharge with normal kidney function represents an early outcome.
Longer follow-up will be needed to determine how well the transplanted kidneys perform over the months and years ahead.
The AIIMS team was led by Prof. Asuri Krishna, with support from the nephrology, anaesthesia, transplant immunology, ORBO and organ retrieval teams.

It is a common belief that metabolic dysfunction-associated steatotic liver disease (MASLD)—formerly known as non-alcoholic fatty liver disease (NAFLD)—is primarily associated with diet, sedentary lifestyles, and obesity. However, there are other factors as well affecting this aspect. Post-menopausal women experience a significantly higher incidence and faster progression of fatty liver disease, even when maintaining a stable body weight.
In pre-menopausal women, oestrogen plays a central role in metabolism, by promoting healthy fat accumulation in subcutaneous tissue (below the skin) rather than around internal organs, it also increases insulin sensitivity and suppresses liver inflammation.
After menopause when oestrogen levels drop, this protective function is lost, there is redistribution of fat leading to more fat accumulation around internal organs including liver thus leading to increase chances of NAFLD and also increasing insulin resistance, needless to say that with age our metabolic rate also goes down which also plays a role in this.

The important part lies not only in understanding above but to go further in early detection and prevention of menopause associated NAFLD. As we know that fatty liver is a silent disease and often does not causes any signs and symptoms till very advanced stage.
First and foremost is to change lifestyle with advancing age, changing both the dietary habits and physical activity. Regular screening and monitoring is warranted with blood tests, routine metabolic panels, keeping a tab on weight, sugar and cholesterol levels and a basic ultrasound of abdomen.
For someone already diagnosed with 2nd or 3rd stage fatty liver, a simple non-invasive. Fibroscan can help monitor and assess the response to treatment.

Coming to treatment part of NAFLD in post-menopausal women, it being primary a lifestyle disease so the core of management also lies around managing lifestyle. Medicines are available for treating and controlling NAFLD in conjunction with lifestyle management.
Hormone replacement therapy (HRT), when initiated early in post-menopausal women for symptomatic relief may offer secondary benefits by maintaining metabolic health. However HRT should always be initiated after proper evaluation and expert guidance.
NAFLD is a silent epidemic and primarily a life style disease, knowing about it and knowing triggering and precipitating factors helps understanding and prevention better.
Menopause being a natural biological phenomenon in every female’s life, it becomes essential for us to know how it affects our liver health and overall health as well.

Every year, as the monsoon rolls in, hospitals and clinics across India see a familiar pattern: a sharp uptick in children and elderly patients presenting with vomiting, diarrhoea, and dehydration.
Doctors attribute this seasonal surge to a combination of contaminated water supplies, deteriorating food hygiene, and warm, humid conditions that favour the spread of viruses like rotavirus and norovirus.
Heavy rains and flooding routinely compromise municipal water lines, allowing sewage to mix with drinking water. Street food and produce are more prone to contamination during this period, and the humidity itself accelerates bacterial and viral growth.
Acute gastroenteritis, an inflammation of the stomach and intestines, is consistently one of the fastest rising monsoon health conditions, with rotavirus being a leading cause in children and norovirus a common culprit across age groups.
Rotavirus is a highly contagious, wheel shaped virus and remains the leading cause of severe diarrhoeal illness and death in children under five worldwide. It spreads through the faecal oral route via contaminated water, food, surfaces, or close contact with an infected person, and can cause several days of intense vomiting and watery diarrhoea, putting young children at real risk of rapid dehydration.
The good news: Rotavirus vaccines, given orally in a series of doses before 8 months of age, are highly effective at preventing severe disease and are recommended as part of national immunisation programmes.
Boil or filter all drinking water during the monsoon months. Avoid ice and beverages of uncertain origin, especially from street vendors.
Steer clear of cut fruits, chaat, and other street food that has been sitting exposed. Cook food thoroughly and eat it hot. Avoid reheated leftovers stored without refrigeration.

Frequent handwashing with soap before eating, after using the toilet, and after changing diapers remains one of the single most effective, low cost interventions against faecal oral transmission.
Ensure infants complete their full rotavirus vaccine schedule on time. Vaccination substantially reduces hospitalisations and severe outcomes, even though it does not eliminate all seasonal transmission.
Because these viruses spread easily within households and childcare settings, keep infected individuals' utensils and linens separate, and disinfect surfaces regularly during an active infection.
Most cases of viral gastroenteritis are self limiting, but caregivers should watch for signs of dehydration that require urgent medical attention:

Oral Rehydration Solution (ORS) is the cornerstone of management.
A simple homemade version consists of 1 litre of boiled and cooled water, 6 teaspoons of sugar, and half a teaspoon of salt. It can be lifesaving when commercial ORS packets are not available, though pre mixed WHO formula ORS is preferable when accessible.
Zinc supplementation (around 20 mg daily for 10 to 14 days) is recommended for children under five, as it has been shown to reduce the duration and severity of diarrhoeal episodes.
Antibiotics are not effective against viral gastroenteritis and should only be used if a bacterial cause, such as cholera, is confirmed by a doctor. Inappropriate antibiotic use can do more harm than good.
Continue feeding. For breastfed infants, continue breastfeeding throughout the illness. For older children and adults, small, frequent sips of fluids and bland, easily digestible food are better tolerated than large meals.
Seek medical care promptly if there is persistent high fever, visible blood in the stool or vomit, signs of moderate to severe dehydration, or if symptoms do not improve within 2 to 3 days, particularly in infants, the elderly, or anyone with underlying health conditions.
