A condition, known commonly as "black urine disease" or Alkaptonuria is a rare genetic disorder involving protein metabolism, and it has its root in the mutation of the homogentisate 1,2-dioxygenase gene, which in turn causes homogentisic acid accumulation in the body. The appearance of dark urine after exposure to air is due to this kind of accumulation; however, a variety of symptoms can be expected, such as joint stiffness, changes in pigmentation, and other long-term health complications. Although the prevalence has been estimated to be between 1 in 250,000 and 1 in 1 million people in the United States, its effects are indeed high on those affected.
Alkaptonuria is an autosomal recessive disease, meaning that the child must inherit a defective copy of the HGD gene from both parents. If both parents are carriers, their offspring have a 25% chance of inheriting two faulty genes and developing alkaptonuria. The condition is genetic but is often not diagnosed for years because it progresses slowly and its early symptoms appear to be harmless.
The most characteristic and common initial symptom of alkaptonuria is dark urine. The reason for this is due to the fact that excess HGA is excreted in the urine and upon oxidation in the presence of air, it gives the urine a brown or black color. Though it is often considered cosmetic, the long-term accumulation of HGA within the connective tissues produces more complicated health problems.
Progressive joint pain and stiffness: The accumulation of HGA in cartilage leads to early-onset osteoarthritis, making movement increasingly difficult over time.
Skin and eye pigmentation changes: Affected individuals may develop bluish or grayish discoloration of the sclera (white part of the eye) and the skin, particularly in areas exposed to friction.
Cardiovascular and respiratory problems: With age, HGA accumulation can lead to valve calcifications in the heart and stiffening of connective tissues in the respiratory tract, which can cause problems in middle and old age.
Decreased mobility and spinal problems: The spine may become stiff and painful due to chronic cartilage degeneration.
These symptoms usually begin to manifest during adulthood, leading to severe complications in a person's 40s or 50s and significantly affecting the quality of their life.
Because of its rarity, alkaptonuria is often mistaken or overlooked early in life. However, there are several ways to confirm the condition:
Urine Testing: The gold standard in the diagnosis is the testing of urine samples for high levels of homogentisic acid via gas chromatography. In case of oxidation, which changes the color of urine to black, it is indicative of alkaptonuria.
Genetic Testing: Confirmatory genetic testing reveals mutations of the HGD gene to diagnose the condition conclusively.
Blood Tests: High levels of HGA in the blood can be used as further evidence.
Imaging Studies: X-rays and MRIs will expose cartilage and joint damage characteristic of alkaptonuria.
At present, there is no cure for alkaptonuria; however, various treatment approaches can reduce its symptoms and slow the disease's progress:
Nitisinone Therapy: Nitisinone is a drug that inhibits the production of HGA. It has been shown to reduce HGA levels and slow tissue damage. However, it needs to be taken under close medical supervision because of potential side effects.
Low-Protein Diet: Since HGA is a byproduct of protein metabolism, reducing protein intake—especially foods rich in tyrosine and phenylalanine—may help decrease HGA production.
Pain Management: OTC pain relievers and anti-inflammatory medications can be used to relieve joint pain and stiffness.
Physical Therapy: Exercise regularly, as it may improve mobility and strengthen muscles, thus reducing strain on affected joints.
Surgical Interventions: Most people with alkaptonuria develop severe osteoarthritis necessitating joint replacement in their old age. Also, some may require heart valve replacement surgery if cardiovascular complications develop.
Although alkaptonuria is not fatal, it severely affects the quality of life. The progressive deterioration of the joints and associated symptoms can make everyday activities difficult, requiring lifestyle changes and medical interventions. The disease may cause premature aging of the joints, requiring walking aids and mobility assistance earlier than expected.
Ongoing research will continue to work on improving the treatment options by focusing on gene therapy and alternative enzyme replacement therapies. However, because of its rarity, the clinical trials and research remain sparse.
As genetic research advances, more hope for better management and possible curative approaches for alkaptonuria exists. Scientists are searching extensively for enzyme replacement therapies and innovative drugs that can target the root cause of the disorder. Being aware and being diagnosed early helps individuals better their condition and ultimately have better long-term health outcomes.
Alkaptonuria is a striking example of how one gene mutation can have widespread effects on the body. Though still a rare and often misunderstood condition, growing awareness and advances in treatment are paving the way for better care. If you or a loved one suspect symptoms of alkaptonuria, it is essential to seek early diagnosis and medical guidance to manage the disease effectively and preserve quality of life.

Robotic surgery has rapidly become one of the most talked-about advances in modern medicine. Yet, for many patients, the technology remains misunderstood.
The first thing to know is that the robot does not perform the operation. Every movement is directed by the surgeon. The robotic platform translates the surgeon’s hand movements into highly precise, tremor-filtered movements inside the body while providing magnified three-dimensional vision and greater instrument dexterity.
The real question, therefore, is not whether robotic surgery is better. It is whether it is the right choice for a particular patient, procedure and surgeon.
For many routine operations, conventional laparoscopy may achieve equally good outcomes. Technology should support clinical judgment, not replace it.
Patients should also recognise that outcomes depend far more on the experience of the surgical team than on the robotic system itself. Successful robotic surgery requires specialised training, structured credentialing and a coordinated operating theatre team.
Choosing an experienced surgeon can therefore be more important than choosing a hospital simply because it owns a robotic system.
Another important development is that robotic surgery is becoming more accessible. Indigenous platforms are helping expand advanced surgical care beyond a handful of metropolitan hospitals by making robotic programmes more viable for a wider range of healthcare institutions.
This gradual decentralisation means patients in Tier II and Tier III cities can increasingly access advanced minimally invasive surgery closer to home, reducing the need to travel long distances for specialised treatment.

Innovation is also extending beyond the operating room. Robotic telesurgery, demonstrated successfully using Made-in-India robotic platforms, has shown that expert surgeons can operate across vast distances using secure digital networks.
While widespread adoption will require robust infrastructure and regulatory frameworks, the technology represents an important step towards improving access to specialised surgical expertise.
Patients should look beyond the hype and ask informed questions:
With indigenous platforms helping decentralise robotic surgery, advanced care is becoming more accessible beyond major metros. The technology has also demonstrated the potential of interhospital telesurgery, enabling expert surgeons to operate across distances and potentially helping bridge gaps in access to highly skilled surgical expertise.
Ultimately, the future of surgery will not be shaped by machines alone. It will be shaped by skilled surgeons using intelligent technology to deliver safer, more precise and equitable patient care.

A cigarette after stress. Chewing tobacco during the day. Smoking to “calm the nerves”
But modern science is forcing us to confront the difficult truth; Tobacco does not treat mental health symptoms, in fact it quietly deepens it.
As Oncologists and physicians, we often see patients who say, “smoking makes them feel normal.” However, in reality, what they are experiencing is nothing more than the temporary relief from nicotine withdrawal not genuine emotional regulation.
When we smoke or chew tobacco, nicotine stimulates dopamine release in the brain, creating a short-lived sense of relaxation or control. But overtime it leads to brain depending on nicotine to achieve the same baseline feeling again and again. The result is a vicious cycle of dependence, irritability, anxiety, and worsening emotional resilience.
Several large studies now show that long-term tobacco use is associated with higher rates of anxiety, depression, sleep issues and substance dependence. A 2023 review published in BMJ found that smoking cessation will result in improvements in both anxiety and depression and an improved mood with benefits comparable to antidepressant treatment in some individuals.

This has serious implications for the urban Indian population in regard to the increasing prevalence of mental exhaustion, lack of social support, digital overload, work-related stress and lack of sleep. Tobacco often enters quietly during vulnerable moments of college pressure, workplace stress, loneliness, grief and gradually shifts from “social habit” to psychological crutch.
Although they think they believe in tobacco, many of them use it, thinking that they are using it to cope with their emotional symptoms, when in fact they are making the symptoms worse.
Also, recognize the biology of tobacco use. For example, the use of nicotine will result in long-term changes in how well your body handles emotional stress because of the role of long-term nicotine exposure in altering the system of cortisol regulation and the stress response pathways in neurons. So, with time, it will become harder and harder for a person to control his/her emotional response to stress because his/her body will not be able to do it. Thus, tobacco has a negative influence on the recovery process from emotional responses to stress, rather than a beneficial one.

Tobacco is a significant preventable risk factor for oral, head and neck, lung, oesophageal, pancreatic and bladder cancers. When many patients arrive at cancer centres, the addiction to tobacco is already set, and it is even more difficult to quit while receiving cancer treatment.
This is why it is important to help move the conversation on tobacco beyond cancer. Now, it's more than just a public health issue; it also includes issues of mental health. Individuals experiencing emotional difficulties should not think that they are being judged. They have to learn to find alternative coping strategies, get psychological support early on in their lives, sleep well, exercise, be part of the community, and access timely medical support. The goal of this care is not just to support someone in quitting tobacco, but to provide support for them to stop needing tobacco in order to feel good.

India is facing a growing burden of non-communicable diseases (NCDs), with hypertension and diabetes among the major health concerns.
Experts warned that the risk of both conditions rises after 40, often without noticeable symptoms. Increasing age, weight gain, reduced physical activity, stress, dietary habits, and metabolic changes can all contribute to the risk.
Having hypertension and diabetes together is particularly concerning, as their coexistence can increase the risk of heart disease, stroke, kidney damage, retinopathy, and other complications.
Dr. Santosh Gupta, Associate Director - CTVS, Paras Health Udaipur, told HealthandMe that several factors contribute to the rising risk after 40.
“After the age of 40, the risk of hypertension and diabetes increases due to factors such as changes in metabolism, reduced physical activity, weight gain, stress and dietary habits. What makes both conditions particularly concerning is that they can develop silently, without noticeable symptoms, while gradually affecting vital organs,” he said.
He added that uncontrolled hypertension can damage the heart, brain, kidneys, and blood vessels, while diabetes can affect the kidneys, eyes, nerves, and cardiovascular system.
"When both conditions occur together, the risk of heart disease, stroke and kidney complications becomes even higher,” Dr. Gupta added.
Because both conditions can remain silent for years, people may have high blood pressure or blood sugar without knowing it.

A recent hospital-based analysis found that hypertension and diabetes frequently occur together, with their coexistence rising sharply from around age 40 among Indians.
The study, conducted by the Department of Clinical Research and Preventive Health Program at Max Healthcare, analyzed health records of more than 56,000 adults who underwent preventive health check-ups between January 2021 and December 2024.
Nearly 5% of adults had both conditions. Their coexistence increased rapidly from around 40, continued rising until approximately 58 and gradually reached nearly 17% by around age 70.
People with diabetes were nearly four times more likely to have hypertension, while those with hypertension were about 2.5 times more likely to have diabetes.
Dr. Abhaya Indrayan, Biostatistics Consultant, Max Healthcare, said the findings support screening for both conditions rather than assessing them separately.

Experts said that preventive healthcare should go beyond checking for individual diseases. Adults over 40 should routinely assess key cardiometabolic risk factors, including blood pressure and blood sugar.
Screening can help detect hypertension, diabetes or prediabetes early, when lifestyle changes and treatment can help prevent or delay complications.
“This is why regular screening after 40 is important, even for individuals who feel completely healthy. A routine blood pressure check, fasting blood glucose or HbA1c test can help identify hypertension, diabetes or prediabetes at an early stage, when timely lifestyle changes and medical intervention can prevent or delay complications,” Dr. Gupta said.
“Screening should not be viewed only as a diagnostic exercise; it is an opportunity to understand one’s health risks and take corrective measures before the disease begins to cause irreversible organ damage,” he added.
Preventive care also involves addressing modifiable risk factors. Regular physical activity, maintaining a healthy weight, limiting salt, sugar and highly processed foods, getting adequate sleep and avoiding tobacco can help lower the long-term risk.
For those already diagnosed with hypertension or diabetes, regular monitoring and adherence to prescribed treatment are important to reduce the risk of complications.
With the risk of both conditions rising after 40, experts recommend making routine health checks part of regular healthcare—even when there are no obvious symptoms.
