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.

Irritable Bowel Syndrome (IBS) is becoming an increasingly important health issue among IT professionals, who are specifically at risk because of certain factors present in corporate culture. There has been a gradual rise in the prevalence of IBS among these individuals over the last ten years, due not only to better diagnosis but also to the accumulation of stress, erratic lifestyles, and physical inactivity.
Dr Sudha Subhana Desai, Senior Consultant in Internal Medicine and Critical Care at Ruby Hall Clinic, Pune, said, "The first factor contributing to the development of IBS in the IT environment is constant psychological stress. Working in the information technology industry requires the ability to meet tight deadlines, maintain high-level performance, and spend many hours in front of a computer while coordinating with colleagues from different time zones. All these activities affect normal circadian rhythms, placing an individual's body under constant stress. This becomes particularly relevant as the connection between the central nervous system and the digestive tract via the gut-brain axis is involved in this mechanism. Thus, constant stress can lead to disturbances in gut motility, increased sensitisation, and an imbalance of the flora. Hence, individuals develop common IBS symptoms such as abdominal pain, bloating, constipation, diarrhoea, or an alternation between these."
Further, Dr Desai spoke about how the dietary practices common among employees in IT professions exacerbate the issue. The expert said that the hectic nature of their work schedules often forces them to resort to unhealthy eating practices, including eating out at fast food restaurants. Their diet often consists of foods lacking dietary fibre but containing high levels of fats, sugars, and additives. This is unhealthy not only because it is nutritionally unbalanced but also because such foods may cause gastrointestinal problems. In addition, their unpredictable work hours make their diet and sleep habits less regular, thus disrupting digestive processes.
Other lifestyle behaviours typical of employees in IT professions put them at higher risk. Firstly, a lack of exercise, which results from long working days, prolonged sitting, and little physical activity, slows down intestinal motility and decreases overall metabolism. Secondly, long screen exposure and sedentary behaviour have the same effect. Thirdly, poor sleep quality, experienced by night shift workers and those responsible for international projects, adversely impacts the hormonal balance necessary for healthy digestion. Lastly, high caffeine intake is typical of these employees, as they use coffee and energy drinks to alleviate fatigue.
While there is increased health consciousness, along with improved availability of medical care, the increase in IBS can only be partially explained by increased diagnoses. Rather, there is an actual increase due to stress factors and living patterns associated with the working environment of the IT industry.
In the treatment of IBS among IT professionals, a number of factors must be addressed in order to help individuals cope with their conditions. One such factor is stress management. Professionals must be taught various methods of coping with stress, ranging from exercises such as yoga and breathing techniques to more structured interventions. The environment must also be conducive to health and well-being. In other words, organisations must facilitate a healthy working environment and encourage individuals to achieve a work-life balance while reducing any workload stresses. Professionals must also make alterations to their dietary habits, including eating regularly, having fibre-rich meals, and avoiding highly processed foods.

Did you know? Discontinuing activities and overly restrictive behaviour, including unnecessary bed rest, does not improve implantation chances when it comes to IVF. Instead, balanced living, moderate activity, proper nutrition, and emotional well-being are important after the procedure. Hence, make sure to follow the advice given by a fertility consultant. Women should prioritise their health.
A failed IVF attempt is not just a financial crisis but also an emotional rollercoaster. For several couples struggling with infertility, IVF offers a ray of hope and may even help them conceive a baby. However, sometimes the attempt can fail due to several reasons, but do not let that affect your motivation to engage in your favourite activities.
Dr Rashmi Agarwal, Fertility Specialist, Nova IVF Fertility, Gurugram, in an interview with Health and Me, spoke about the rising incidence of infertility in young couples, and how following a restricted behaviour may only lower the odds of conceiving a baby.
Infertility cases are rising among couples. There are a large number of couples who struggle with infertility and opt for in vitro fertilisation (IVF). However, couples tend to have doubts regarding it. For those who undergo IVF, the period after embryo transfer is filled with hope, anxiety, and a strong urge to “do everything right”. Many women feel that after the procedure, complete bed rest, taking it easy, and avoiding any activity can increase the chances of pregnancy. However, maintaining a balanced routine is often more beneficial than extreme rest.
After embryo transfer, many patients assume that movement could disturb implantation, and they suddenly avoid all activities without asking the doctor. They try not to walk, work, or do any household chores. But do not worry or panic, as the embryo is safely placed inside the uterus and cannot “fall out” with normal movement. The body is naturally designed to support implantation. There is no evidence available that claims that strict bed rest improves success rates. However, staying inactive for long periods can lead to stiffness, poor blood circulation, and increased stress or anxiety, which can take a toll on overall well-being.
How to improve chances of IVF success
Light activities like walking, gentle stretching, and routine household tasks are generally safe, as recommended by the doctor. Eating a nutritious diet, staying hydrated by drinking 3–4 litres of water per day, de-stressing by doing meditation or reading, and getting enough sleep can be beneficial for women. Many women can also overthink, become anxious, and constantly worry about pregnancy. Hence, opting for relaxing activities like deep breathing, meditation, reading, staying connected with loved ones, and maintaining a positive mindset can help patients cope better during the waiting period, although it is not advised to overexert or do any strenuous activities without the doctor’s knowledge.
Following the expert’s instructions without fail, staying active, doing light exercises, and paying attention to physical and emotional well-being can support a smoother IVF journey.
World Malaria Day: Avoid going outdoors in the evening without a mosquito repellant. (Photo credit: iStock)
Delhi-NCR witnessed unexpected showers in the city this year in the month of April. Before the heatwave could get as severe as it usually is every season, there were a few days where the national capital witnessed refreshing showers—but as it turns out, these showers often increase the risk of diseases like malaria. Yes, unexpected showers may bring temporary relief from heat, but they also quietly reset the risk for diseases like malaria. The concern today is not just rainfall, but how changing climate patterns are shifting the timeline of disease transmission—often weeks before the monsoon fully arrives.
Ahead of World Malaria Day, Dr Suranjit Chatterjee, Senior Consultant-Internal Medicine, Indraprastha Apollo Hospital, Delhi, spoke about the effects of such unexpected rains ahead of the monsoon season.
Malaria has long been seen as a monsoon-linked illness, but that pattern is changing. Intermittent rainfall, rising temperatures, and increased humidity are now creating ideal breeding conditions much earlier in the year. Even a short spell of rain can lead to water accumulation in urban areas—on terraces, construction sites, in clogged drains, and in poorly managed storage spaces. These become hidden breeding grounds for mosquitoes, accelerating their life cycle and increasing the risk of early transmission.
From a healthcare perspective, this shift is significant. The first fever after early showers is often overlooked or dismissed as a seasonal viral infection. However, malaria in its early stage can closely resemble common viral illnesses, presenting with symptoms such as fever, chills, headache, body ache, and fatigue. This overlap frequently delays diagnosis. Any fever that persists beyond 2–3 days, recurs, or does not respond to basic treatment should be tested promptly. Early detection remains critical to preventing complications.
Early malaria can look like a common viral fever. The symptoms of the disease are:
Waiting for the monsoon to begin preventive action is no longer effective. The response must start with the first signs of rain. Clearing drains, eliminating stagnant water, monitoring construction zones, and ensuring proper waste management are essential early steps. At the household level, covering water containers, maintaining clean terraces, and regular checks for water accumulation can significantly reduce risk. Some of the key precautions to take against malaria are the following:
A year-round public health priority
World Malaria Day serves as a reminder that malaria prevention is not seasonal—it is continuous. In an era of unpredictable weather patterns, cities and communities must adapt quickly. Acting only when cases begin to rise means reacting too late. The real shift lies in recognising that prevention must begin with the first unexpected shower, not the peak of the monsoon.
