Have you ever been in such a deep slip and ended up waking coughing? Chances are, you choked on your own saliva. Yes, it is very much possible. Saliva is a clear liquid produced by your salivary glands that play a crucial role in digestion and oral health. This is because it washes away bacteria and food particles. The body on an average produces about 1 to 2 litres of saliva daily, and a lot of it is swallowed unconsciously. However, when saliva does not flow smoothly down the throat, it can lead to choking, which can be uncomfortable.
Here's all that you need to know about what causes it, and how can you prevent it.
This happens when the muscles that are responsible for swallowing weaken or malfunction due to health issues and the symptoms may include:
Some of the common reasons include:
Acid reflux occurs when stomach acid travels back into the esophagus and mouth, irritating the esophagus and increasing saliva production to neutralize the acid. This buildup of saliva can lead to choking.
Acid reflux can be diagnosed via endoscopy or X-rays. Treatment includes antacids to reduce stomach acid.
When you are sleeping, some abnormal swallowing can occur during that time and it may cause saliva to pool in the mouth and flow into the lungs. This is what leads to choking. This condition is often linked to obstructive sleep apnea (OSA), which causes breathing to pause during sleep.
CPAP machines to provide continuous airflow
Oral mouth guards to keep the airway open
Growths in the throat, whether benign or cancerous, can narrow the esophagus and impede swallowing.
Treatment may involve surgery, radiation, or chemotherapy, depending on the nature of the growth.
Dentures can confuse the brain into perceiving them as food and it may trigger excess saliva production and cause choking. The best way to work this out is by consulting a dentist for proper fitting and adjustment of dentures.
Conditions like Parkinson’s disease and ALS can impair the nerves that control swallowing.
Doctors may prescribe medication to reduce saliva production or teach swallowing techniques.
Excessive alcohol consumption can relax throat muscles, allowing saliva to pool and cause choking.
Moderate alcohol intake and sleep with your head elevated.
Speaking continuously without pausing to swallow can lead to saliva entering the windpipe.
Take pauses to swallow while talking.
Thickened saliva or mucus due to allergies or infections can obstruct the throat, especially during sleep.
Antihistamines, cold medication, or antibiotics may be prescribed, depending on the underlying cause.
In case of sleep apnea, sleep with your head elevated or on your side. You can also try and avoid lying flat right after eating and eat smaller meals to prevent acid reflux. It is also important that you sip water throughout the day to clear any saliva buildup. In severe cases, use over-the-counter medicines for allergies or consult a healthcare provider.

Vitiligo is an acquired disorder of depigmentation characterized by white patches on the body. It affects all races. There is a lot of stigma associated with the disease due to disfigurement. The affected persons suffer from psychological distress, low self-esteem, and social neglect. Inadequate knowledge and age-old misconceptions are the key reasons for this undue apprehension associated with this condition.
Common Myths About Vitiligo
There is a misconception that vitiligo can spread by contact. However, vitiligo is non-contagious and does not spread by contact.
Another misconception is that sour food causes vitiligo, which is not scientifically proven. It cannot be transmitted through contact, shared items, or proximity. It is not caused by bacterial, viral, or other infectious agents. It tends to be more noticeable in people with darker skin, due to higher contrast between affected and unaffected areas.
There is no significant variation in people of different races, religions, and socio-economic status for predisposition to vitiligo. There is another myth that vitiligo and leprosy are the same, as both present with white skin.
The exact cause is multifactorial, with hypotheses based on genetic—autoimmune, neural, and biochemical theories. There is a role of acquired factors like stress and infections in its clinical expression. It is associated with other autoimmune disorders like diabetes mellitus, alopecia areata, Addison's disease, and thyroid disorders.
The course of the disease is unpredictable. If you notice any skin discoloration, reach out to a dermatologist for early diagnosis and treatment.
Bust the myths about vitiligo with proper information regarding the condition.
By proper public awareness, the social stigma associated with the condition can be debunked. A qualified dermatologist can diagnose the condition with medical history, Wood's lamp examination, and blood tests to rule out other autoimmune diseases.
There is no cure for vitiligo, but treatment to restore pigmentation and to prevent progression of the disease can be done. Counseling and support groups to help patients with this disorder can make a meaningful difference.

Fentanyl is an FDA-approved, quick-acting narcotic painkiller that is nearly 100 times more potent than morphine and 50 times stronger than heroin. While it has important medical uses, widespread illicit use has created a public health crisis, with researchers now warning that commonly used addiction treatments are struggling to keep pace.
A study by researchers at the University of California, Los Angeles, found that people who regularly use illicit fentanyl consume opioid doses equivalent to morphine levels hundreds of times higher than the fentanyl doses used in hospitals—far beyond what current addiction treatment protocols were designed to address.
Published in the journal Drug and Alcohol Dependence, the findings suggest these extreme exposure levels contribute to high opioid tolerance, making medications for opioid use disorder (MOUD) less effective and increasing overdose risk.
Although methadone and buprenorphine remain highly effective at reducing overdose deaths, many patients have struggled to start and remain on treatment since fentanyl replaced heroin as the dominant illicit opioid in the US because of the severity of fentanyl withdrawal, the team said.
The researchers estimated fentanyl exposure using morphine milligram equivalence (MME), a standardized measure that compares the potency of different opioids.
The analysis combined purity data from more than 500 fentanyl samples collected by Drug Checking Los Angeles between September 2023 and January 2026 with surveys of 47 people who regularly used fentanyl.
The researchers estimated that participants consumed an average of 8,887 MME per day.
According to the US Centers for Disease Control and Prevention (CDC), just 2 mg of fentanyl can be lethal for an opioid-naïve person. The study found that the average fentanyl user in Los Angeles consumes roughly 60 times that amount each day.
Tolerance develops not only to the drug's intoxicating effects but also to the respiratory depression that causes overdose, said Dr. Chelsea Shover, associate professor in the Department of Health Policy and Management.
"Now, we find that people are regularly exposed to doses of opioids that would have seemed impossible to me before I started this work," Shover said.
"To put it in perspective, in hospital settings, fentanyl is often dosed in 100-microgram vials. One gram of average-purity fentanyl that we tested had a dose equivalent to more than 1,200 of these vials. So people are getting daily doses that are on par with injecting hundreds of the hospital vials or taking 440 Percocet pills."
According to the researchers, the potency and variability of illicit fentanyl mean that people are consuming opioid doses far beyond what existing treatment protocols were designed to manage.
"Of course, starting MOUD is going to be harder for fentanyl than it is for heroin," Shover said.
"This study is a great example of where our science was directly informed by lived experience. It is a call to take withdrawal management seriously, with adjuvant therapies, and compassionate approaches."
As a fully synthetic drug, fentanyl is cheaper and easier to produce than heroin. Its high potency also increases the risk of unintentionally consuming dangerous amounts, raising the likelihood of overdose.
"It's no longer, 'how do we treat someone who smokes a gram of fentanyl per day,' it's 'how do we treat someone using thousands of MMEs of oral morphine in fentanyl per day?' That question and its answers feel more accessible, less abstract to clinicians," Shover said.
The study reinforces concerns among addiction experts that standard treatment regimens for opioid addiction may no longer adequately address patients with extremely high fentanyl tolerance.
Current doses of medications such as buprenorphine and methadone were originally developed to treat heroin and prescription opioid addiction. The findings add to growing calls from clinicians to update treatment guidelines to reflect today's illicit fentanyl market.
"When patients say their withdrawal is not being treated well, it's important to listen," Shover said.

Athletes who spend years training their bodies undergo remarkable physiological changes. Athlete's heart is one of them. It becomes stronger, more efficient, and sometimes even larger. This natural adaptation is known as athlete's heart, a condition that is completely normal in most cases but can occasionally resemble serious heart disease.
Understanding the difference between a healthy athletic heart and an underlying cardiac disorder is crucial, especially as awareness grows around sudden cardiac deaths in young athletes.
HealthandMe spoke to Dr. Ruchit Shah, Interventional Cardiologist at Saifee Hospital, Mumbai, who said, “If a person exercises too much, normally more than 60 minutes in most days of the week for a prolonged period of time, the body's need for oxygen and for blood to supply the oxygen rises significantly. This can often be seen in the very intense training regimens of competitive athletes. The heart muscle responds to this extra demand by getting "conditioned" and thickening with time.”
Just like skeletal muscles that get bigger and thicker and with training and exercise, the heart muscle can get bigger and thicker too.
Athlete's heart is usually characterised by a “conditioned heart rate”. People with athlete's hearts will now show symptoms or serious warning signs and thereby won't need a specific treatment for the condition.

Signs include:
The expert also says that athlete's heart is different from serious cardiac diseases like cardiomyopathies, especially hypertrophic obstructive cardiomyopathy (HOCM).
He says, “HOCM is a serious disease, with heart muscle thickening also occurring and causing the left ventricular cavity to narrow. The left ventricle's outflow tract can also become obstructed from this excessive thickening. Athletes with HOCM have a risk of sudden cardiac arrest and death, unlike athletes with athlete's heart.”
An athlete‘s heart, by itself, is considered a benign physiological adaptation and does not require medical intervention.
However, it becomes important to investigate further if an athlete experiences:
Ignoring these warning signs can delay the diagnosis of potentially serious cardiac conditions. Those who have an athlete’s heart must get periodic cardiac evaluation, do a temporary reduction in training if the diagnosis remains uncertain, and monitor when minor abnormalities are present.
Athlete's heart is proof of the body's extraordinary ability to adapt to sustained physical activity. For most athletes, it represents a healthy, efficient cardiovascular system rather than a medical problem. The challenge lies in distinguishing these normal adaptations from potentially dangerous heart conditions that can look remarkably similar.
