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.

When we talk about cancer prevention, the conversation usually turns to individual choices. Whether someone smokes, what they eat, how much they exercise, or how regularly they visit a doctor. These are important considerations, but they do not tell the whole story. A person's surroundings can influence their health in ways that are not always immediately apparent. The air they breathe every day, the conditions in which they work, the food they can afford and the healthcare available to them can all have a bearing on their risk of developing cancer.

In clinical practice, cancer rarely has one identifiable cause. It develops through a combination of factors, including age, genetics, infections, lifestyle and environmental exposure. Some of these can be modified. Others are tied to circumstances that people have little control over.

The air we breathe and the work we do

Air pollution is generally discussed in the context of respiratory and cardiovascular illness. Its association with cancer, particularly lung cancer, deserves equal attention. Fine particulate matter from vehicle exhaust, industrial emissions, construction dust and waste burning can remain in the air people breathe over long periods. Indoor air quality is another concern. In homes where wood, coal or other biomass fuels are used for cooking, poor ventilation can expose families to harmful smoke over many years.

The workplace presents a different set of risks. Construction workers, miners and employees in certain manufacturing industries may regularly come into contact with substances such as asbestos, silica dust and diesel exhaust. Prolonged exposure to these carcinogens is associated with specific cancers. The risk is not simply a matter of the nature of the job, but also the conditions under which it is performed. Protective equipment, adequate ventilation and routine workplace monitoring are therefore essential, not optional safety measures.

What ends up on the plate is not always a choice

Diet is another area where personal circumstances matter. What a person eats is influenced by affordability, availability, working hours and household responsibilities. A consistently poor dietary pattern, particularly one high in processed meat and low in fibre, is associated with an increased risk of certain cancers. Excess body weight is also linked to several cancers, including colorectal, endometrial and postmenopausal breast cancer.

This does not mean that eating a particular food will cause cancer, or that avoiding one ingredient will prevent it. The concern is with patterns that develop over time, alongside other risk factors. Advising people to eat better is only useful when that advice considers what they can realistically afford and access.

Why some communities face greater challenges

The same health advice does not translate into the same opportunities for everyone. People living in congested neighbourhoods may have limited control over their exposure to pollution. Workers in informal or unregulated sectors may not have access to adequate protective equipment or occupational health services.

These circumstances can also determine how quickly someone receives a diagnosis. A persistent cough, unexplained weight loss, a breast lump or unusual bleeding may initially be dismissed. For someone who has to travel long distances, lose a day's wages or pay out of pocket for investigations, seeking medical attention is not always straightforward. By the time they reach a specialist, the disease may have progressed.

Early detection, therefore, is not just about recognising symptoms. It also depends on whether people can access a doctor, undergo the necessary investigations and complete their follow-up care.

Prevention has to go beyond individual choices

There are established ways to reduce cancer risk. Avoiding tobacco, limiting alcohol, maintaining a healthy weight and staying physically active all matter. HPV and hepatitis B vaccination can help prevent cancers associated with these infections. Screening for breast, cervical and oral cancers should be undertaken as recommended, based on age and individual risk. A persistent or unusual symptom should always be evaluated rather than left unattended.

But prevention cannot stop at the doctor's consultation room. Cleaner air, safer workplaces, better housing and affordable diagnostic services need to be part of the larger conversation.

A person's risk of cancer is shaped by more than the choices they make. It is also influenced by the conditions in which they live, work and seek care. Recognising this is important because prevention becomes meaningful only when people have a fair opportunity to act on it.

Winter brings a significant rise in respiratory problems, particularly among people living with asthma. Increased air pollution, falling temperatures and exposure to dust and other airborne irritants can trigger inflammation in the airways, leading to symptoms such as coughing, wheezing, chest tightness and breathlessness.

While these factors can make asthma more difficult to manage, many patients also make treatment-related mistakes that can worsen their symptoms and increase the risk of an asthma attack.

One of the most common mistakes is discontinuing inhalers when symptoms improve. Asthma is a chronic inflammatory condition, and the absence of symptoms does not necessarily mean that the underlying inflammation has resolved. Controller inhalers, particularly those containing inhaled corticosteroids, help reduce airway inflammation and prevent flare-ups.

Stopping these medications without medical advice can leave patients vulnerable to sudden exacerbations, especially during periods of high pollution.

Another concern is the excessive reliance on rescue inhalers. These inhalers provide quick relief by relaxing the muscles around the airways, but they do not necessarily address the underlying inflammation. Frequent use may indicate that asthma is not adequately controlled and that the patient's treatment plan needs to be reviewed by a doctor. Patients should not increase their medication dosage or frequency without appropriate medical guidance.

Incorrect inhaler technique is another frequently overlooked problem. Patients may use their inhalers too quickly, fail to coordinate inhalation with medication release or neglect to hold their breath briefly after inhaling. These mistakes can prevent the medicine from reaching the lungs effectively. Regularly reviewing inhaler technique with a healthcare professional and using a spacer, where recommended, can significantly improve drug delivery.

Many patients also underestimate the importance of continuing their prescribed treatment during symptom-free periods. Some turn to steam inhalation, home remedies or over-the-counter cough medications instead of following their asthma management plan. Although certain supportive measures may provide comfort, they cannot replace prescribed asthma medication. Hot steam can also cause burns and should not be used as a treatment for asthma.

During winter, patients should monitor local air quality, reduce prolonged outdoor exposure when pollution levels are high, avoid tobacco smoke and other respiratory irritants, and keep their prescribed medication accessible. Wearing a well-fitting mask outdoors may help reduce exposure to particulate pollution, although it does not eliminate the risk.

Most importantly, people with asthma should have an individualised asthma action plan and attend regular follow-ups. Worsening breathlessness, difficulty speaking in full sentences or symptoms that do not respond to the prescribed reliever require urgent medical attention. With correct inhaler use, consistent treatment and timely medical review, most patients can manage their asthma more effectively even during highly polluted winter months.

Changes in stride like a slower walking pace, fewer steps or a change in the way your arms move may be considered as signs of ageing. However, an emerging study suggests that minor differences in walking patterns could be subtle, early indicators of Parkinson’s disease. According to the study, these signs can can emerge years before Parkinson's diagnosis.

Published in the Journal of Neural Transmission, the study analysed movement data from more than 73,000 participants in the UK Biobank. Researchers found that certain changes in walking behaviour could indicate a future Parkinson’s diagnosis, surfacing up to 6.8 years beforehand.

The findings indicate that Parkinson’s disease may begin developing long before its more familiar symptoms like tremors and stiffness, become noticeable.

Findings From The Study

Researchers examined data from 73,413 people who wore wearables that track movement for seven days. Their health records were then followed for up to 10 years. Of the participants without Parkinson’s at the time of the movement assessment, 314 were diagnosed with the disease during follow-up.

Using a digital analysis tool called Watch Walk, researchers examined 17 characteristics related to gait. They identified five walking characteristics that were consistently linked with a subsequent Parkinson’s diagnosis:

• Fewer steps each day: Participants who later developed Parkinson’s recorded lower daily step counts than those who did not.
• Slower walking speed: People who were diagnosed later tended to walk more slowly, including at their maximum walking speed.
• Shorter walking periods: They also spent a lesser amount of their time walking in longer, continuous stretches.
• Changes in step regularity: Their steps showed less consistent rhythm, indicating alterations in the regularity of their walking pattern.
• Reduced natural arm swing: They spent more time walking with their arms in a static position instead of swinging naturally.

Parkinson’s disease is a progressive neurological disorder that affects movement. It occurs due to the loss of nerve cells that produce dopamine in a brain region called the substantia nigra. Dopamine helps regulate movement, coordination and other functions.

As dopamine levels decline, the brain's ability to coordinate movement is affected. This can lead to bradykinesia, or slowness of movement, rigidity of muscle, tremors and balance issues.

These changes can also affect gait. A person may take smaller steps, walk more slowly, experience difficulty moving or reduced swinging arms.

The study's findings suggest that some of these motor changes may be detectable in everyday movement well before the condition is formally diagnosed.

Changes in walking speed, balance, step length or arm movement can occur for several reasons, including ageing, joint problems, injuries, medication effects and other neurological conditions.

Parkinson’s disease is, however, diagnosed through a clinical assessment, which considers a person's symptoms, medical history and neurological examination. Other symptoms that may warrant medical evaluation include:

• A tremor especially when the affected hand or limb is at rest.
• Slowness in everyday movements like dressing or getting up from a chair.
• Muscle stiffness or rigidity.
• Problems with balance.
• Smaller handwriting or changes in speech volume.

Early Detection Of Parkinson’s Disease

Although there is currently no established treatment that stops or reverses the underlying progression of Parkinson’s disease, an earlier diagnosis can help people manage symptoms, access rehabilitation and support sooner.

Exercise, physiotherapy and medical care can help maintain mobility, balance and quality of life. Early assessment can also help doctors distinguish Parkinson’s from other conditions that may cause similar movement difficulties.
