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.

How to recognize the symptoms of choking on saliva?

This happens when the muscles that are responsible for swallowing weaken or malfunction due to health issues and the symptoms may include:

• Gagging and coughing without eating or drinking
• Gasping for air
• Inability to breathe or speak
• Waking up coughing or gagging

What are the common reasons? Why does it happen?

Some of the common reasons include:

Acid Reflux

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.

Other symptoms of acid reflux:

• Heartburn
• Chest pain
• Nausea

Diagnosis and Treatment:

Acid reflux can be diagnosed via endoscopy or X-rays. Treatment includes antacids to reduce stomach acid.

Sleep-related Swallowing Disorders

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.

What are the treatment options?

CPAP machines to provide continuous airflow

Oral mouth guards to keep the airway open

Lesions or Tumors in the Throat

Growths in the throat, whether benign or cancerous, can narrow the esophagus and impede swallowing.

Symptoms to Watch For:

• Visible lump in the throat
• Hoarseness
• Sore throat

Treatment:

Treatment may involve surgery, radiation, or chemotherapy, depending on the nature of the growth.

Dentures That Don't Fit

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.

Neurological Disorders

Conditions like Parkinson’s disease and ALS can impair the nerves that control swallowing.

Additional Symptoms:

• Muscle weakness or spasms
• Difficulty speaking

Treatment:

Doctors may prescribe medication to reduce saliva production or teach swallowing techniques.

Heavy Alcohol Use

Excessive alcohol consumption can relax throat muscles, allowing saliva to pool and cause choking.

Prevention Tip:

Moderate alcohol intake and sleep with your head elevated.

Talking Excessively

Speaking continuously without pausing to swallow can lead to saliva entering the windpipe.

Prevention:

Take pauses to swallow while talking.

Allergies or Respiratory Problems

Thickened saliva or mucus due to allergies or infections can obstruct the throat, especially during sleep.

Additional Symptoms:

• Runny nose
• Sore throat
• Sneezing

Treatment:

Antihistamines, cold medication, or antibiotics may be prescribed, depending on the underlying cause.

How can you prevent choking from saliva?

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.

Brain disorders are becoming one of India's fastest-growing public health challenges, said health experts ahead of Brain Day on July 22.

The experts highlighted that an ageing population, rising lifestyle diseases and limited access to specialist care are contributing to an increasing burden of conditions such as stroke, epilepsy, Parkinson's disease, dementia and multiple sclerosis.

Access Gap Delays Diagnosis, Treatment

Dr. Madhukar Bhardwaj, Director & Head of Department, Neurology, Aakash Healthcare, said neurological disorders have become one of India's most urgent healthcare concerns.

"Neurological disorders are no longer a concern of a small section of the population—they are one of the most pressing emerging healthcare challenges of our time. In a country as vast and diverse as India, with a rapidly ageing population, this is a matter of urgency. What makes the situation even more worrying is the lack of equitable access to care," he said.

According to the World Health Organization's Global Status Report on Neurological Disorders (2025), India faces a severe shortage of neurologists, with the neurologist-to-patient ratio nearly 80 times worse than in high-income countries, leaving specialist care concentrated in major cities.

Stroke Increasingly Affects Younger Adults

Experts also highlighted a worrying shift in disease patterns, with strokes increasingly affecting younger people. Dr. Bhardwaj said strokes, once considered a disease of older adults, are now being seen more frequently among people in their 30s and 40s, underscoring the need for greater awareness and prevention.

Lifestyle Diseases Driving Brain Disorders

Doctors identified uncontrolled hypertension, diabetes, obesity, smoking, chronic stress, physical inactivity and poor sleep as major contributors to the rising burden of neurological diseases.

Dr. Rajas Deshpande, Consultant and Head of Neurology, Jupiter Hospital, Pune, said many neurological conditions share common lifestyle-related risk factors.

"Controlling hypertension, diabetes, obesity, smoking and physical inactivity can significantly reduce the risk of stroke and vascular dementia. Prevention deserves as much attention as treatment because many neurological disorders share common modifiable risk factors," he said.

Early Diagnosis Can Improve Outcomes

Dr. Bhardwaj stressed that many neurological disorders progress silently, making early diagnosis critical.

"Whether it is stroke, epilepsy, Parkinson's disease or memory disorders, early diagnosis can significantly improve outcomes. Unfortunately, many patients seek specialist care only after the disease has advanced, either because symptoms are ignored or because neurological services are not easily accessible. Greater public awareness and timely referrals are essential," he said.

Brain Health Linked to Women's Reproductive Health

Experts also emphasized that brain health extends beyond cognition. Dr. Hrishikesh Pai, Consultant Gynecologist & IVF Specialist, Lilavati Hospital Mumbai and Fortis Hospitals Delhi & Chandigarh, said the brain plays a central role in regulating women's reproductive health.

"Brain health plays a critical role in women's reproductive health. The hypothalamus and pituitary gland in the brain regulate the hormonal signals that control menstruation, ovulation, and pregnancy," he said.

He added that chronic stress, neurological disorders, pituitary diseases and certain medications can disrupt hormonal balance, leading to irregular menstrual cycles, infertility and pregnancy-related complications.

As wildfire smoke continues to affect communities across North America and Europe, fertility experts are recommending people undergoing vitro fertilization (IVF) to pay attention to an overlooked factor before embryo implant: air quality.

A new study suggests that exposure to unhealthy levels of air pollution, particularly from wildfire smoke, could significantly reduce the chances of a successful pregnancy after IVF.

Researchers, therefore, recommend discussing the timing of embryo transfer with a fertility specialist when air quality deteriorates.

Wildfire Smoke May Interfere With Embryo Implantation

The study, published in the journal Human Fertility, indicates that air pollution may affect reproductive health.

Between June and July 2023, researchers from Northwell Fertility in New York examined 190 fresh and frozen embryo transfers, when smoke from massive Canadian wildfires caused hazardous air quality across the northeastern United States.

They then compared the rate of successful pregnancies based on the Air Quality Index (AQI) on the day of embryo transfer.

Clinical pregnancy rates were approximately 62% on days with good air quality and 65% on days with moderate air quality.

But when the AQI rose above 100, a level considered unhealthy for sensitive groups; the pregnancy rate dropped to just 27%.

Although only 11 embryo transfers took place on days with unhealthy air quality, the researchers say the findings raise concerns about whether temporary exposure to wildfire smoke could affect one of the most critical stages of IVF.

How Can Air Pollution Affect Fertility And IVF Success Chances?

IVF embryos are created and stored in strictly controlled laboratories, meaning they are protected from polluted air and other contaminants in the environment.

Instead of damaging the embryo, researchers believe that wildfire smoke can affect the woman's body by increasing inflammation and oxidative stress. This could create a less favourable environment for the embryo to implant in the uterus.

Air pollution contaminant, PM2.5, a fine particulate matter, is one of the main pollutants in wildfire smoke. It is minute enough to enter the lungs, bloodstream, and trigger inflammatory responses throughout the body.

Previous studies have already indicated that PM2.5 exposure could cause pregnancy complications and harm fertility.

Dr. Randi Goldman, Program Director at Northwell Fertility and co-author of the study, said the research suggests patients and physicians should consider environmental conditions when planning embryo transfer.

"The embryo is safely protected inside the laboratory. The effect we're seeing is more likely related to how air pollution influences the body before and after embryo transfer rather than the embryo itself," Goldman said.

She opines that patients experiencing severe wildfire smoke or hazardous air quality should discuss whether delaying embryo transfer by a few days could improve the chances of success.

"Patients invest enormous emotional, physical and financial resources into IVF. Delaying treatment is difficult, but when air quality reaches unhealthy levels, it may be worth discussing timing with your fertility specialist," Goldman said.

Expert-Recommended Tips To Improve IVF Success

Adopt a Fertility-Boosting Lifestyle: Eat a balanced diet, exercise daily, and enjoy a healthy BMI. Reduce alcohol intake, do not smoke, and avoid recreational drugs.

Take Key Supplements: Folic acid, CoQ10, and vitamin D can improve egg quality and overall fertility.

Stress Management Is Key: Elevated cortisol levels can affect reproductive hormones. Practice mindfulness, yoga, or acupuncture.

Sleep Well: Aim for at least 7–8 hours of restful sleep to support hormonal balance.

Address Underlying Health Conditions: Conditions such as PCOS, thyroid issues, and endometriosis can interfere with fertility outcomes if left unmanaged.

Start Early, If Possible: The earlier IVF is initiated—especially for women over 35—the better the chances.

The detection of the Omicron RF.5 subvariant in Andhra Pradesh has raised concerns about a possible resurgence of COVID-19 in India. However, health experts say there is no evidence so far that the new sub-lineage causes more severe illness than other recently circulating Omicron variants.

While RF.5 may spread more efficiently, experts stress that the focus should remain on protecting vulnerable groups rather than panicking.

RF.5 Transmissible, Not More Deadly

Speaking to HealthandMe, Dr. Aijaz Ilmi, Senior Consultant – Preventive Wellness & Metabolic Diseases, Pacific OneHealth Hospital, said the detection of RF.5 should prompt vigilance, not fear.

"At present, there is no convincing evidence that RF.5 causes more severe disease than other recently circulating Omicron variants, although it may spread efficiently. Ongoing surveillance remains essential, as seen in Telangana."

Dr. Tushar Tayal, Associate Director, Internal Medicine, CK Birla Hospital, Gurugram, added that countries including Singapore have already detected RF.5 without reporting a corresponding rise in hospitalizations, suggesting the variant may be more transmissible but not more severe.

Mild Illness For Most Healthy People

Dr. G.C. Khilnani, Chairman, PSRI Institute of Pulmonary, Critical Care, told HealthandMe that the current outbreak is being driven by the Omicron variant, which generally causes a milder upper respiratory illness than earlier COVID-19 strains.

He said healthy individuals typically experience fever, cough, runny nose and body aches, while the risk of severe disease remains much lower than during previous waves.

"This virus remains confined to the throat, or what we call the oral cavity, and does not traverse to the lungs. Therefore, in a normal healthy individual, it does not cause pneumonia. So, it is not life-threatening in immunocompetent or healthy individuals."

Who Is at Risk?

Following four COVID-19-related deaths reported in Andhra Pradesh over the past two weeks, experts said people with weakened immunity continue to face the highest risk of severe illness. This includes cancer patients undergoing chemotherapy, people with uncontrolled diabetes, older adults, those on long-term steroid therapy and people living with HIV/AIDS.

"Most infections are expected to present with mild upper respiratory symptoms such as sore throat, fever, cough, runny or blocked nose, fatigue, headache and body aches," Dr. Ilmi said.

He added that older adults, pregnant women, people with heart, lung or kidney disease, obesity, cancer, diabetes, weakened immunity and those who are inadequately vaccinated remain the most vulnerable to severe COVID-19.

Experts said RF.5 does not appear to cause unusual symptoms. Common signs include:

• Sore throat
• Fever
• Cough
• Runny or blocked nose
• Fatigue
• Headache
• Body aches

They advised seeking immediate medical attention if symptoms such as breathlessness, persistent chest pain, confusion or low oxygen levels develop.

COVID-19 in India: Vigilance, Not Panic

India has reported a renewed uptick in COVID-19 cases, with 339 infections recorded between July 1 and July 16, according to the Andhra Pradesh Health Department.

Reported cases during this period include:

• Kerala: 115
• Karnataka: 64
• Maharashtra: 43
• Tamil Nadu: 39
• Andaman and Nicobar Islands: 18
• Delhi: 18
• Rajasthan: 12
• Other states: Remaining cases

How To Prevent

Experts said public health guidance has not changed despite the emergence of RF.5. They recommend wearing masks in crowded places, getting tested if symptoms develop, and isolating after a positive test to reduce transmission.

Dr. Khilnani also stressed the importance of early diagnosis, avoiding crowded places while infected, wearing a mask and following proper cough etiquette. He added that people with weakened immunity should be especially cautious, avoid crowded settings and maintain good hand hygiene.

Early testing, adequate hydration, rest and symptomatic treatment remain the cornerstone of management, particularly for high-risk individuals.
