The heat waves are rising all over the world and causing a lot of damage. While there are issues of dehydration and heat strokes, studies are suggesting that it might also be responsible for declining mental health, the heat among other things is not only affecting the physicality of human beings but is also having adverse mental health.

Emotional distress: The heat can trigger mood swings, making you feel irritable, anxious, depressed, or even aggressive. You may not be able to predict your reaction, you may be good one moment and then any minor inconvenience will make you angry or sad. Heat often triggers that helplessness in people.

Scattered Focus: Concentrating on tasks becomes a struggle when it's hot. Simple things feel overwhelming, and staying focused is a challenge. While you may be in the zone working on completing something, the heat and sweating will disrupt your flow and then you will not be able to focus on anything other than the heat.

Sleepless Nights: High temperatures, especially at night, disrupt your sleep. This lack of rest can leave you feeling tired, and grumpy, and worsen existing mental health issues. All humans require a comfortable temperature to sleep in, if your body is too wound up or heated up, it will not be able to relax and sleep.

Feeling the Pressure: The heat can pile on stress and make you feel overwhelmed. Concerns about the heat itself or its impact on other aspects of your life can contribute to this feeling. You will feel overwhelmed and unable to work on anything else. The heat makes you feel a certain helplessness, as you cannot stop the sun or turn down the heat.

Body Blues: The heat can cause physical symptoms that affect your mental well-being. Headaches, fatigue, dizziness, and nausea can all contribute to anxiety and low mood. When your body is already fatigued, the urge to do anything else disappears. Your body is drained of energy to function at all and will seek rest and sleep.

Behavioural Shifts: The heat can influence your behaviour. You might act impulsively or have difficulty managing anger. It's like the heat turns up your emotional thermostat. When your body and brain are overheating, it is difficult to think straight and you will grasp at straws to release this energy and pressure off of you.

Some other side effects of the heat are.

  • Mental Health Flare-Ups: If you already have a mental health condition, hot weather can worsen your symptoms. Existing depression, anxiety, bipolar disorder, or schizophrenia might feel more intense.
  • Heat and Suicide Risk: Studies show a disturbing link between hot weather and increased suicide rates, particularly among men and older adults. Hot weather can be a tipping point for those already struggling.
  • Heatwave Hospitalizations: When temperatures soar, people with existing mental health issues may require increased hospitalization. This highlights the need for healthcare systems to be prepared for heat waves.
  • Climate Change and Mental Health: Climate change is leading to more frequent heatwaves. Research suggests this could lead to a rise in mental health problems and suicides. Taking action against climate change is crucial for protecting mental well-being.

Common metabolic conditions such as obesity and diabetes are increasingly becoming a serious public health concern in India. Their health implications extend beyond the conditions themselves, with obesity and diabetes associated with a range of chronic diseases and complications that can affect long-term health and wellbeing. As lifestyles become more sedentary and the prevalence of these conditions continues to rise, understanding their wider implications on women’s health is becoming increasingly important.

What many women may not realize is that this metabolic burden can carry a deeper, less visible consequence one that reaches into the domain of gynecological cancer.

One such concern is endometrial cancer. A form of uterine cancer, it develops in the lining of the uterus and is becoming an increasingly important health issue globally. Yet, many women remain unfamiliar with the disease, its risk factors, and the symptoms that require prompt medical attention.

The Metabolic Health Connection

Increasing evidence points to a link between metabolic syndrome and endometrial cancer, particularly through conditions such as obesity and diabetes. Excess body weight and metabolic disturbances can disrupt hormonal balance, such as by increasing estrogen production without a corresponding increase in progesterone. Over time, this hormonal imbalance may stimulate abnormal growth of the endometrial lining, increasing the likelihood of cancer development.

Diabetes, too, has been associated with an increased risk. As obesity and diabetes become more prevalent, recognizing these less-discussed consequences is an important part of strengthening women’s preventive health.

For women, maintaining a healthy weight, staying physically active, managing metabolic conditions effectively and paying attention to unusual symptoms can all form part of a broader approach to preventive health.

Watching Out For Unusual Symptoms

One of the most important characteristics of endometrial cancer is that it often presents with abnormal vaginal bleeding. Bleeding or spotting after menopause is one of the most significant warning signs and should never be ignored.

For women who have not reached menopause, heavier-than-normal periods, prolonged bleeding, or bleeding between periods should be discussed with a healthcare professional.

Why Awareness Matters

Improving awareness is important because there is currently no recommended routine screening test for endometrial cancer in asymptomatic women. As a result, recognizing symptoms and seeking timely medical advice are among the most effective ways to support earlier diagnosis.

At the same time, the conversation should not end with cancer awareness alone. As India continues to face a growing burden of obesity and diabetes, prioritizing metabolic health has become increasingly important for overall wellbeing.

Maintaining a healthy weight, staying physically active, eating a balanced diet, and effectively managing conditions such as diabetes can help reduce the risk of a range of serious health complications, including certain cancers. For women, understanding the connection between metabolic health and endometrial cancer can empower more informed decisions about prevention, symptom recognition, and long-term health. By addressing obesity and diabetes early and seeking medical advice when unusual symptoms arise, women can take meaningful steps towards protecting their health at every stage of life.

Stage IV Melanoma: When a Difficult Cancer Shows an Unexpected Response

Updated Aug 31, 2026 | 07:32 AM IST

SummaryStage IV melanoma can sometimes show remarkable responses to treatment, highlighting how advances in immunotherapy and targeted therapies are changing outcomes even in advanced disease.

Melanoma is often considered one of the more challenging cancers to treat, particularly when it has spread to distant organs. For early-stage disease, surgery remains an important treatment option. But once melanoma reaches stage IV, treatment becomes considerably more complex.

Understanding The Biology Of Advanced Melanoma

According to Dr. Mandeep Singh Malhotra, Cheif Mentor AOHC, cytotoxic chemotherapy has traditionally had a limited role in melanoma, while immunotherapy has changed the treatment landscape for many patients.

When melanoma is detected at an early stage and can be completely removed, surgery is generally considered the preferred treatment. Depending on the disease, this can involve removal of the primary tumour and assessment or treatment of regional lymph nodes.

But stage IV melanoma presents a very different challenge.

A Complex Case With Multiple Tumour Sites

Dr. Malhotra recalls the case of Sarah, who came to the team with multiple nodules in the scapular region. There were also lesions on both legs and a lesion in the pancreas. So there were multiple nodules. One in the right side of the leg, another in the left side of the leg. And there was a lesion in the pancreas.

Rather than relying on a standard treatment approach alone, the team first tried to understand the biology of the disease. As a standard protocol for this type of case, we first try to understand the disease biology. In Sarah’s case, the team used extensive testing, including chemosensitivity testing, transcriptomic analysis and next-generation sequencing.

When Imaging Initially Suggests Progression

The results suggested sensitivity to certain drugs. When we analysed those reports, we were able to understand that cytotoxic drugs like temozolomide were effective. And checkpoint inhibitors like pembrolizumab, nivolumab were effective.

Based on these findings, the team developed a treatment protocol in which the main component was an immune checkpoint inhibitor along with low-dose temozolomide. Other agents, including lower doses of anti-VEGF, anti-FGF and CDK inhibitors, were also incorporated based on the analysis.

After around four weeks, the response became difficult to interpret on imaging. The PET scan suggested that all the lesions have had a pseudo progression.

Pseudo progression is a recognised phenomenon during immunotherapy. A tumour may appear larger initially because of immune-cell infiltration, even when the treatment is actually producing an anti-tumour response.

This is particularly relevant in melanoma treated with immune checkpoint inhibitors. However, doctors cannot simply assume that every apparent progression is pseudo-progression; true progression must also be considered and confirmed through Histopathology

Histopathology Reveals A Dramatic Treatment Response

The team then proceeded with surgery, removing the nodules from the scapular region and both thighs. The specimens were sent for histopathological examination. And histopathology results were amazing. The tumours had gone necrotic.

The pathology showed extensive treatment-related changes, with inflammation and fibrosis around the nodules and only small areas containing viable melanoma cells.

What Comes Next For The Patient?

For now, the plan is to continue the treatment for a few more cycles and then reassess the pancreatic lesion. The team is considering NanoKnife (irreversible electroporation) for the pancreatic lesion followed by Vaccines.

Certain cancer vaccines are being developed in certain labs in Germany and Europe and they are available for our patients in India on compassionate grounds. It's a very, very good response. And to achieve disease NED in stage four melanoma, I think we are really lucky and it's all due to the grace of God.

Why Individualised Treatment Matters In Stage IV Disease

The case also highlights an important point about advanced melanoma: treatment may need to be individualised according to the biology of the disease and the patient's response. At the same time, he stresses the need for hope. I hope that more people can benefit from this protocol and use this protocol to treat melanomas across the world.

For Sarah, the journey is still ongoing. The next step will be to reassess the pancreatic lesion and determine whether further local treatment can help achieve no evidence of disease (NED). A stage IV melanoma involving multiple sites, including the pancreas, reaching a point where NED may become a possibility is certainly an encouraging development. But it remains an individual clinical experience, rather than proof that the same protocol will work for every patient with metastatic melanoma.

Why People Living With Obesity Should Get Their Liver Checked Early?

Updated Aug 30, 2026 | 07:00 PM IST

SummaryPeople living with obesity have a higher risk of fatty liver disease, which can progress silently. Early liver checks can help detect damage and enable timely intervention.

People living with obesity and diabetes often feel healthy in their day-to-day life, but some of the most dangerous changes may be happening silently inside their bodies.

The liver is one of the first organs to be affected. In many cases, fat slowly accumulates in the liver without causing any pain, discomfort, or obvious symptoms. This is why fatty liver disease is often called a “silent condition.” By the time it is detected, it may already have progressed to an irreversible stage.

Excess body fat, particularly around the abdomen, disrupts how the body processes sugar and fats, placing continuous stress on the liver. Because of this silent progression, experts now strongly recommend that people living with obesity and type 2 diabetes should proactively check their liver health, even when they feel completely well.

Obesity is closely linked with liver damage through a series of metabolic changes that develop over time. When the body becomes resistant to insulin, fat begins to accumulate in liver cells, triggering inflammation and gradual injury.

If this continues unchecked, the condition can progress from simple fat accumulation to more serious stages, including metabolic dysfunction-associated steatohepatitis (MASH), where inflammation and liver cell damage become more significant.

Over time, this may lead to fibrosis (scarring of the liver), and in advanced cases, cirrhosis, which can severely affect liver function. Further, patients with fatty liver may directly present with liver cancer, which can occur in up to 20% of patients.

How Common Is Fatty Liver In People With Diabetes And Obesity?

In India, the burden of metabolic dysfunction-associated steatotic liver disease (MASLD) or fatty liver is rising and is now recognised as a common metabolic condition. Studies from the Indian subcontinent estimate that 1 in 3 people may have MASLD. Fatty liver is particularly common among individuals with metabolic risk factors.

It is seen in nearly 40–80% of people with type 2 diabetes and 30–90% of those with obesity, often without clear symptoms.iv Hospital-based trends also suggest increasing detection in younger age groups, reflecting changes in diet, reduced physical activity, and more sedentary lifestyles.

What Liver Checks And Preventive Measures Should You Follow?

Preventive measures to be followed:

  • If you live with excess weight/obesity and type 2 diabetes or PCOS (polycystic ovarian syndrome) or dyslipidemia, seek early consultation with a physician or hepatologist.
  • Your doctor may request routine metabolic screening:
  • Regular liver function tests as part of annual health check-ups
  • Ultrasound screening for individuals with obesity or diabetes
  • Monitoring blood sugar, cholesterol, and triglyceride levels
  • Liver scarring scan (annually for patients with diabetes/obesity)
  • Avoiding long-term neglect of “mild” or borderline test results

With rising obesity rates in India, early liver screening should become a routine part of preventive healthcare. Even modest weight reduction, improved diet quality, and regular exercise (approximately 150 minutes per week of moderate-intensity exercise (example: brisk walking, gardening, swimming, cycling) or 75 minutes of vigorous exercise (example: weight training) can significantly reduce liver fat and inflammation within 3-6 months.

However, once the disease progresses to MASH or fibrosis, reversal becomes more difficult and may require long-term medical management. Early-stage fatty liver disease is reversible in many cases. In fact, medications can even reverse liver fibrosis (early scarring), but in only 25% of patients. Simple homemade food is sufficient to prevent these lifestyle diseases, and there is no need for “fancy online diets or supplements”.

Our forefathers lived longer by consuming homemade food and water without any supplements. Newly approved therapies such as semaglutide (GLP1 analogues) have been shown to resolve steatohepatitis and reduce liver fibrosis. These liver benefits do not appear to be explained solely by weight loss, suggesting a broader potential impact on liver health.

The absence of symptoms does not mean the absence of risk. Taking care of the liver early is not just about preventing disease; it is about protecting long-term health, energy, and quality of life.
