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.

Why Does Smoking Affect Your Physical Appearance?

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."

Visible Signs Of Smoking

Here are some visible signs of smoking in people, according to 2013, Lung India

Fingers and Nails

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.

Moustaches

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.

Lips

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.

Teeth

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.

Premature Wrinkling

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.

Nodular Elastosis

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.

Facial Wrinkling and COPD

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.

Rebecca Pinto, physiotherapist and nutritionist shared a video on her Instagram account where she cites a case of a man who used hair loss treatment and was admitted to hospital on complain of chest pain. She points out that not everything that is available over the counter is safe to use. She says the key ingredients in many easily available hair loss treatment is minoxidil, which could trigger chest pain or angina as it can lower blood pressure.

Health and Me spoke to Dr Sanjay Bhat, Sr Consultant, Interventional Cardiology at Aster CMI Hospital, Bengaluru to fact check this claim and here is what we found out.

Fact Check: Can Minoxidil Cause Severe Chest Pain?

Health and Me asked Dr Bhat if this easily available ingredient could actually cause someone’s life. To this, Dr Bhat explained that it is a commonly used medicine for treating hair loss and is easily available in many pharmacies as a topical solution or form. He said it works by improving blood flow to the hair follicles and helping hair grow. “When used on the scalp as recommended, it is generally safe for most people. However, long-term or excessive use may sometimes cause side effects. Some people may absorb a small amount of the medicine into the bloodstream, which can affect the heart and blood vessels,” he explains.

This could lead to symptoms such as chest pain, rapid heartbeat, dizziness, swelling of the hands or feet, or low blood pressure. “In rare cases, people may go to the emergency room if they feel severe chest discomfort or palpitations. Long-term use without medical advice may also cause scalp irritation or unwanted hair growth on other parts of the body. Therefore, it is important to use minoxidil only as directed and consult a doctor if unusual symptoms appear,” he said.

What To Do If You Feel Chest Pain While Using Minoxidil?

Doctor explains, “If a person develops chest pain after using Minoxidil, the first step is to stop using the medicine and seek medical attention immediately. Doctors will first evaluate the patient to make sure the chest pain is not due to a serious heart problem. This usually includes checking blood pressure, heart rate, oxygen levels, and performing tests such as an electrocardiogram (ECG) and blood tests.”

If minoxidil is suspected to be the cause, treatment mainly focuses on managing the symptoms. Doctors could also give medicines to control heart rate, reduce palpitations, or stabilize blood pressure. Depending on the reports, if the patient has fluid retention or swelling, diuretics may be prescribed to remove excess fluid from the body. Patients may also be monitored in the hospital for a short time if symptoms are severe. Once the symptoms settle, doctors usually advise avoiding minoxidil and may suggest safer alternative treatments for hair loss.

Are There Any Alternative Hair Loss Treatment Without Minoxidil?

The answer is yes. Dr Bhat points out Finasteride, an oral medicine to be one of the common alternatives to minoxidil for hair loss treatments. This medicine works by reducing the hormone DHT, which is linked to male pattern baldness. This also helps in slowing down the hair loss and promoting regrowth.

Platelet Rich Plasma Therapy: This is another alternative available points out Dr Bhat. This is when blood is processed and injected into the scalp to stimulate hair follicles and improve hair thickness.

He also pointed out that doctors often recommend Low Level Laser Therapy, which is a painless treatment using red light lasers to improve blood flow to hair follicles and encourage hair growth.

Lastly, Hair Transplant Surgery is another option for people facing significant hair loss, where follicles from one part of the scalp are moved to bald areas.

“In addition, treatments such as microneedling, nutritional supplements, and treatment of underlying medical conditions may also help improve hair growth,” points out Dr Bhat.

Leucovorin, a high-dose vitamin - folinic acid, were mostly used for treating toxic side effects of chemotherapy, until last year when the White House touted it as a potential treatment for some children with autism. New prescriptions for leucovorin double within weeks of announcement and parents have been trying hard to get it prescribed. This is also because many doctors have been hesitant to prescribe a chemotherapy medicine for childhood autism. They have also stated that not enough evidence is available to prescribe this drug officially.

CNN reported that in Austin, Texas, Meagan Johnson spent four days calling pharmacies across the region searching for leucovorin for her three-year-old son Jack, who has autism. She contacted nearly 40 pharmacies around her home in Pflugerville, hoping to locate the medication.

The effort came after a neurologist agreed to prescribe leucovorin on a trial basis. Johnson’s hope was simple: even a small improvement in her son’s communication would mean a lot. At age three, most children can say hundreds of words, but Jack speaks only about 20, many of which only his mother understands.

However, getting the prescription turned out to be far harder than obtaining it.

Across the United States, pharmacies have been reporting growing difficulty keeping leucovorin tablets in stock. Online support groups for parents of autistic children are now filled with posts from families searching for the medication or asking where it might still be available.

Although leucovorin is not approved specifically for autism, some small studies have suggested that it may help certain children who have unusually low levels of folate in the brain. Families who have tried it report possible improvements in language and social interaction.

A study published in The Lancet found that prescriptions for leucovorin doubled within weeks of the public remarks and remained elevated through early December. Researchers analysed electronic medical records covering nearly 300 million patients to identify the trend.

Experts say such spikes can quickly strain the supply of inexpensive generic drugs.

A Classic Demand-Driven Shortage

Pharmacy supply specialists describe the leucovorin situation as a demand-side shortage. Unlike manufacturing disruptions, these shortages happen when demand rises faster than manufacturers can increase production.

Generic drug manufacturers typically plan production schedules a year or more in advance. Because leucovorin had historically been a niche medication, companies were not prepared for a sudden surge in prescriptions.

As demand increased, pharmacies began running out of tablets. Many manufacturers have placed the drug on allocation or backorder, meaning pharmacies can only order limited quantities.

To ease the pressure, the US Food and Drug Administration allowed temporary imports of leucovorin tablets from Canada and Spain. However, the drug has not yet been officially listed on the FDA’s national drug shortage database, a designation that could trigger additional measures to boost supply.

Families Searching For A Treatment

For parents like Johnson, the debate over research evidence matters less than the possibility of progress.

After days of phone calls, a CVS pharmacist finally located a supply at another branch nearly an hour away. Johnson drove the distance to pick up the medication and gave Jack his first dose that same evening.

The moment brought relief, but also frustration.

Drug shortage advocates say the situation was predictable. Because leucovorin is inexpensive and historically prone to shortages, any sudden increase in demand could easily disrupt supply.

Still, families continue to search for it.

Childhood obesity has been rising steadily across the world, including in India. According to the World Health Organization, the number of children aged 5 to 19 who are overweight or obese has increased more than tenfold over the past four decades.

In India, the Indian Council of Medical Research reports that about 14 percent of children aged 6 to 19 are overweight or obese, with higher rates in urban areas.

Many efforts to prevent obesity focus on healthy eating and physical activity. While these remain essential, research increasingly shows that the stress levels of parents can play a big role in shaping children’s health outcomes.

Stress, simply put, is when the body feels under pressure. Mentally, emotionally, or physically. Parents under stress may have less patience, lower energy, and less ability to maintain healthy routines for their family.

How Parental Stress Leads Childhood Obesity

Additionally, a Obesity Reviews 2017 study also found that parents who suffer from high stress levels are more likely to have irregular eating patterns, snack on unhealthy foods, and engage in less physical activity, which contributes to stressful home environments.

This often leads to a pattern of “comfort eating” and fewer structured meal routines in the house, habits that can be easily picked up and adopted by children. This can pave the way for multiple chronic conditions to develop early on in young children.

Socioeconomic pressures can also worsen the risk of obesity in youngsters. Families experiencing financial stress, job insecurity or long working hours may rely more on convenient fast foods or skip family meals altogether.

According to the World Health Organization (WHO), diet and lifestyle patterns learned in early childhood often persist into adolescence and adulthood, which makes early interventions critical.

How Parenting Styles And Household Atmosphere Matter

A 2020 study in Pediatric Obesity showed that children whose parents reported higher stress levels were more likely to gain excess weight over two years compared with children whose parents reported lower stress.

The home environment can shape a child’s relationship with food. If meals are rushed, distracted, or emotionally tense, children may associate eating with stress rather than nourishment. On the other hand, family routines that include relaxed meals, shared cooking, and parental involvement in active play are linked to healthier weights and better mental health outcomes.

Steps Parents Can Take To Monitor Obesity

• Mindfulness and relaxation techniques: Simple breathing exercises, meditation, or even quiet reading time can lower stress levels. Psychologist Susan Albers notes that mindful parenting improves parent-child interactions and can reduce unhealthy eating patterns.
• Structured routines: Regular meal times, scheduled physical activity, and predictable sleep patterns create stability for children.
• Self-care: Parents who prioritize sleep, exercise, and mental breaks are better able to support their children’s health.
• Healthy family meals: Cooking together, reducing ultra-processed foods, and encouraging fruits and vegetables fosters both nutrition and bonding.

It’s important to note that stress management alone is not enough. Combining emotional support for parents with healthy eating and activity habits is the most effective approach. The American Academy of Pediatrics highlights that integrated strategies addressing diet, activity and family wellbeing can reduce childhood obesity risk more effectively than focusing on nutrition or exercise alone.

Why This Matters For The Future

The impact of a calm, supportive home can be profound. When parents manage stress, children not only eat better and move more, but they also develop emotional resilience and lifelong healthy habits. As Dr. Epel explains, “A child’s wellbeing often mirrors the adult they live with: less stress in parents can mean a healthier start for children.”
