When something is going wrong in your body, there will be signs. They may be subtle, but they are visible in close observation. If you are a smoker, you may be worried about the smell of smoke emanating from your mouth or clothes. However, there are other signs that tell whether you smoke or not and these signs are difficult to get rid of!
Smoking is the harmful act of inhaling tobacco infused smoke and is a common activity all over the world. According to the Center of Disease Control and Prevention (CDC), over 480,000 deaths happen each year due to smoking or smoke inhalation. The organization explained that smoking causes harm to nearly all organs and quitting lowers the risk of early death and other smoking related diseases.
Like many other substances, there are clear tell-tale signs when someone is smoking. This is especially important for finding lung problems like Chronic obstructive pulmonary disease (COPD), which is a lung disease that makes it hard to breathe, sooner so people can get help.
Action on Smoking and Health (ASH) explains that tobacco smoke has more than 7,000 harmful chemicals like nicotine, carbon monoxide, and various metals like arsenic, cadmium, and lead, quickly reach your lungs and then travel through your blood to all your organs, including your skin. Smoking damages your skin's ability to heal because it increases an enzyme metalloproteinase (MMPs) that breaks down collagen. Collagen is what keeps your skin smooth and elastic. As you lose collagen, your skin sags. Squinting from the smoke and puckering your mouth when smoking also cause wrinkles around your eyes and mouth.
Smoking also reduces blood flow to your skin, which means it gets less oxygen and nutrients. All these things together lead to what doctors call a "smoker's face." Quitting smoking can help prevent or slow down these skin problems."
Here are some visible signs of smoking in people, according to 2013, Lung India
When people smoke, the tar and other chemicals in the smoke stick to their fingers and nails. This repeated contact causes a yellow stain that's hard to wash off. It's a very common sign that someone regularly handles cigarettes or biris.
Especially in older people with white moustaches, smoking causes a yellowing effect. This is most noticeable in the center of the moustache, where the smoke from the nose directly hits the hair. The consistent exposure to smoke colors the hair over time.
Heavy smokers often have a bluish-black tint to their lips. This discoloration happens because the chemicals in tobacco smoke affect the blood flow and the color of the skin on the lips. The constant exposure changes the lip's natural color.
Smoking causes teeth to stain both inside and out. The outside of the teeth turns yellow from the tar, while the inside develops a brownish-black stain. This happens because the smoke seeps into the enamel and discolors the teeth over time.
Smoking makes the skin age faster. This leads to wrinkles like "crow's feet" around the eyes and "cobblestone wrinkles" on the neck. This happens because smoking reduces blood flow, limiting oxygen to the skin, and damages collagen, which keeps skin elastic.
This condition, also known as "Favre–Racouchot syndrome," causes blackheads and wrinkles, especially around the eyes and temples. It is made worse by both sun exposure and heavy smoking. The skin becomes discolored with visible nodules and wrinkles.
A study published in Thorax 2006 found a connection between wrinkles on the face and COPD, a lung disease. It's thought that smoking affects both the skin and lungs through similar processes. If doctors notice signs like "crow's feet" on a smoker's face, they might recommend tests for COPD. This early detection can help people get treatment sooner and improve their lung health.

Fructose, found in all processed foods such as sodas and snacks, may not just be adding to your calories. A new study warns about its significant role in the rising metabolic diseases.
The study, published in the journal Nature Metabolism, showed that fructose may be playing a distinct role in driving metabolic disease, acting as a signal that promotes fat production and storage.
“Fructose is not just another calorie,” said lead author Richard Johnson, professor at the University of Colorado Anschutz.
“It acts as a metabolic signal that promotes fat production and storage in ways that differ fundamentally from glucose,” he added.
In the study, the researchers examined how common dietary sweeteners, including table sugar (sucrose) and high-fructose corn syrup, impact human health.
While both contain glucose and fructose, fructose has unique metabolic effects that may more directly contribute to obesity and related conditions.
“Its metabolism bypasses normal energy regulation, leading to increased fat synthesis and lower cellular energy, processes linked to obesity, insulin resistance, and cardiovascular risk,” revealed the researchers.
As the body can produce fructose internally from glucose, the team pointed out that its impact on disease may be broader than just dietary sugar intake.

The study also outlined how fructose metabolism bypasses key regulatory steps in the body’s energy-processing pathways.
This can lead to
“This review highlights fructose as a central player in metabolic health,” said Johnson. “Understanding its unique biological effects is critical for developing more effective strategies to prevent and treat metabolic disease.”
The World Health Organization (WHO) advises that added sugars must make up fewer than 10 per cent of your daily total energy intake, better yet, aiming for 5 per cent for optimal health gains—approximately 25 grams or 6 teaspoons a day for an adult eating 2,000 calories a day.
The American Heart Association (AHA) is even more stringent:
Women: Restrict to 100 calories/day of added sugars (approximately 25 grams or 6 teaspoons).
Men: Restrict to 150 calories/day (approximately 38 grams or 9 teaspoons).
You're taking in too much added sugar if:
While sugar in whole foods such as fruits and vegetables isn't the problem—it's part of a nutrient-dense package, the problem lies with the sneakily added sugars in everyday products such as ketchup, cereals, salad dressings, protein bars, and "health" drinks.
Instead of being afraid of all sugar, pay attention to where it's coming from. Read labels carefully. Stick to whole foods, avoid processed items. While natural sugars in your bowl of fruit or glass of milk may not be a problem, keep an eye out for the syrup in your coffee or that "healthy" granola.
Natural sugars can absolutely be part of a balanced, healthy diet. However, the body doesn’t distinguish between a sugar cube and a fruit smoothie when it comes to blood glucose spikes. What makes all the difference is the nutritional context.

Israeli Prime Minister Benjamin Netanyahu has announced successful treatment for early-stage prostate cancer and stated that he is “in excellent physical condition” now and that there is "no trace left of it".
The small tumor was discovered during a routine checkup, the 76-year-old leader informed on the social media platform X.
Netanyahu had a surgery on his prostate in 2024 after he was diagnosed with a urinary tract infection resulting from a benign prostate enlargement. Since then, he has been under routine medical monitoring.
“In the last monitoring, a tiny spot of less than a centimeter was discovered in the prostate,” he said in the post, adding that it was “a very early stage of a malignant tumor, with no spread or metastases”.
Netanyahu noted that his doctors gave him two options – either not to treat and keep monitoring or to “undergo treatment and remove the problem”.
However, sensing a “potential danger, I want to address it immediately,” he said, citing his character, which stands “true on the national level and also on the personal level”.
“I underwent targeted treatment that removed the problem and left no trace of it. I went to a few short treatments, read a book, and continued working. The spot disappeared completely. Thank God, I overcame this too,” the Israeli Prime Minister said while thanking doctors.
Netanyahu also advised people to “take care of health. Get checked, and follow the doctors' instructions”.

The prostate is the walnut-sized gland in the male reproductive system that makes seminal fluid.
Dr. Srikanth Munna, Consultant Urology, Andrologist, Laparoscopy and Penile Implant Surgeon at KIMS Hospital, Hyderabad, told HealthandMe that it is the most common type of slow-growing cancer in men that sees the abnormal growth of cells in the gland.
Importantly, if detected early, it is very much curable.
Age, family history, or lifestyle choices are the most common risk factors.
Prostate cancer treatment guidelines have shifted their path a bit in recent years, with many men opting for active surveillance rather than immediate treatment for slow-growing tumors.
However, about 50 per cent of men on "watchful waiting" will require further treatment within 5 years because of the tumour progression. A simple Prostate-Specific Antigen (PSA) blood test can help rule out the risk, Dr Munna said

Not all prostate problems are indicative of cancer. While prostate cancer is a serious concern, other conditions can cause similar symptoms but are non-cancerous. One common condition is benign prostatic hyperplasia (BPH).
Experts state that nearly every individual with a prostate will experience BPH as they age. It leads to the enlargement of the prostate gland but does not increase the risk of cancer.
Another condition is prostatitis, which primarily affects men under 50. It is characterized by inflammation and swelling of the prostate, often due to bacterial infections. Early diagnosis can help manage these conditions effectively.
The management and prevention of IBS require a comprehensive approach. (Photo credit: iStock)
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.
