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.

One in four or 25 percent of adults with type-2 diabetes in India also suffer from liver fibrosis, according to an alarming study published in The Lancet Regional Health Southeast Asia journal today.
With data from more than 9,000 patients across the country, it is the largest ever real-world survey of liver fibrosis in type 2 diabetes from any low- or middle-income country.
While fatty liver disease has been touted as the most common liver condition among diabetes patients, the new study established liver fibrosis as the real danger among people with high blood sugar.
“Type 2 diabetes is closely linked to fatty liver disease (also known as MASLD). But how common is liver Fibrosis — the real danger — in Indian diabetics? Our answer: 1 in 4 has clinically significant liver fibrosis. One in 20 already has probable cirrhosis. Most had no symptoms. We propose liver fibrosis as the ‘4th major complication’ of diabetes,” said Ashish Kumar, from Ganga Ram Postgraduate Institute of Medical Education and Research (GRIPMER), from Sir Ganga Ram Hospital, in a post on social media platform X.
What Did The Study Find?
Fatty liver is typically the first and reversible stage of liver disease, where excess fat builds up in liver cells. Left untreated, it progresses to liver fibrosis, which is the excessive accumulation of scar tissue (collagen) in the liver resulting from chronic inflammation. The condition then progresses to the third and late stage, irreversible scarring (fibrosis) of the liver. The final stage is liver cancer.
The DiaFib-Liver Study included a total of 9,202 adults with type-2 diabetes patients who underwent FibroScan (VCTE) to assess liver fibrosis in routine diabetes care.
Of these:
The study suggested the urgent need to integrate fibrosis screening into national diabetes programs.
“One in four adults with type 2 diabetes in India has clinically significant liver fibrosis and one in twenty already has probable cirrhosis, establishing advanced liver disease as a 'fourth major complication' of diabetes,” said the researchers.
“The DiaFibLiver Study calls for: Fibrosis — not steatosis — as the screening target. FibroScan integration into routine diabetes care. Moving beyond ultrasound-based referral,” Jha said.
“We hope this data from India adds to the global conversation on diabetes and liver disease,” he added.

The findings highlight the urgent need to:
Certain lifestyle choices can accelerate liver damage, such as:
Overeating processed or fried foods
High sugar intake (soft drinks, sweets, desserts)
Physical inactivity or prolonged sitting
Ignoring health issues like diabetes or hypertension
Crash dieting or taking unprescribed supplements.
Early screening and detection are key to prevent irreversible stages. Yet liver disease can be prevented with lifestyle changes such as:
Taking too many decisions in a day can lead to mental exhaustion. (Photo credit: iStock)
New Delhi: Every day, the brain processes hundreds of choices. Most pass unnoticed: what to wear, which route to take, what to eat. But accumulated over hours and across competing demands, this constant decision-making exacts a cost. Decision fatigue is the gradual erosion of the brain’s capacity to make good choices, and over time it affects both mental functioning and physical health. Dr Shivi Kataria, Consultant – Psychiatry, CK Birla Hospitals, Jaipur, addressed the problem of plenty and said that it could take a toll on mental health in certain circumstances.

What are the signs?
The earliest signs tend to be emotional. Simple decisions start to feel disproportionately heavy. Choosing between two options takes longer than it should. Irritability surfaces. Tasks that once felt manageable begin to pile up as the mental energy required to engage with them thins. Procrastination, self-doubt, and a general withdrawal from decisions are common responses, with the brain essentially rationing what little capacity remains.
Cognitive symptoms follow. Concentration narrows. Judgement becomes less reliable. Small errors accumulate. People in this state often describe feeling mentally stuck, present in the room but unable to engage with any clarity or momentum.
The physical dimension is frequently overlooked. Headaches, low energy, disrupted sleep, and difficulty sustaining attention are all associated with sustained decision overload. These symptoms register what prolonged mental strain produces in the body and are worth taking seriously.

Who is most at risk?
Decision fatigue affects most people at some point, but the load is not evenly distributed. Professionals in high-responsibility roles, caregivers, and anyone managing multiple competing demands make a disproportionately high number of decisions each day. By the end of a long day, the quality of choices made about food, purchases, relationships, or work often reflects exhaustion more than intention.

Is there a solution?
Reducing the number of decisions that require active thought each day is the most direct intervention. Fixed routines for meals, schedules, and recurring tasks remove the need to deliberate repeatedly over the same ground. This is conservation of mental energy, and it compounds over time.
Important decisions are better made earlier in the day, when the brain is rested and cognitive resources are intact. Short breaks during sustained work periods allow partial recovery. Even brief physical activity or deliberate rest between decision-heavy tasks restores some capacity.
The brain has a finite decision-making budget each day. Spending it on low-stakes choices leaves less available for the ones that carry real consequence.

While fevers are often overlooked and brushed aside or even managed with antibiotics — a dangerous trend — an alarmingly nationwide study linked it to infectious diseases with far-reaching consequences.
The report, based on data of over one lakh individuals in India with fever, between 2023 and 2025, showed that these were not vague or self-limiting, but in more than 30 percent or one-third cases had clear links to serious infections, such as dengue, and typhoid.
According to the report by healthcare diagnostics company Thyrocare, the fevers were mostly linked with
Importantly, the findings highlighted the presence of co-infections in 10 per cent cases. The most common was a combination of dengue and typhoid.
Dr Preet Kaur, Chief Scientific Officer, Thyrocare, said that a significant number of patients carry serious infections, sometimes more than one at a time, revealing patterns that simple assumptions cannot capture.
"Beyond the visible rise in temperature, laboratory markers highlight hidden stress on organs, from drops in platelet counts to elevated liver enzymes, underscoring that fever is a systemic signal, not an isolated event," she added.

Further, the report noted that dengue positivity declined significantly over the three-year report period, malaria increased despite its lower overall base.
Typhoid and chikungunya rose in 2024 before easing in 2025 but remained present across the testing population.

The report noted that more women were affected with typhoid than men. On the contrary, men reported more malaria cases.
More than 32 percent of females had fevers compared to 29 percent of men. Fevers in women was largely driven by higher typhoid detection (21 percent vs 15 percent).
Malaria affected men more than twice as often as women (1.1 percent vs 0.5 percent).
The lab reports also revealed key physiological markers such as platelet counts and liver function among people with fever, dengue, and malaria.
Low platelet levels were seen in
Dengue cases rose throughout the year and typically peaked around October.
Typhoid positivity steadily fell from 2023 to its lowest in 2025. Despite a mild monsoon spike each year, 2025 remained consistently lower overall.
Chikungunya cases rose gradually from lower, volatile levels in 2023, peaked sharply in 2024, and moderated to a softer trend in 2025.
Malaria positivity remained relatively low overall but increased during the monsoon months, with transmission peaking between May and September.
Over the three-year period, malaria positivity rose from 0.5 percent to 1.1 percent, indicating a gradual increase despite its lower overall base.
