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.

Being aware of personal and family cancer risk may be a critical component in women's knowledge and empowerment to make appropriate screening, prevention and treatment decisions.
Cancer treatment is fast evolving. Doctors are now focusing more on the person than the location or type of cancer and are considering the personal attributes of the patient and the disease. Genetic/genomic testing can complement this and can offer something more that could inform personalised cancer care.
Genetic testing screens for changes in the genes that could be passed down from parents. Some genetic mutations passed down from parents can make a woman more likely to get breast or ovarian cancer.
Having such a genetic change does not mean that a woman will develop cancer. This information will help her and her doctor discuss screening, monitoring and preventive action (if applicable) to reduce her risk.
This information may be useful for family members who could be at risk and should talk to their health care provider about their own risk.
There is a difference between genetic testing and genomic testing. Genetic testing is usually performed on blood or saliva to look for inherited changes or genetic predisposition. Genomic testing is usually performed on the tumour or blood to identify its molecular features to enable better understanding of its biology and biomarkers.
Cancer is not one disease and even two patients with the same type of cancer can have different biological characteristics, which can help doctors decide on the treatment and options that may be suitable for an individual patient.
Genomic testing could help to pinpoint features of a tumour that can be used to consider particular targeted treatments or other methods. But not all of them will be suitable or available to all patients based on the results of testing.
For women, knowing their family history and discussing any concerns with a doctor can be an important starting point. Genetic or genomic testing should not be done simply because it is available. A specialist may recommend testing based on factors such as family history, age at diagnosis and the type of cancer involved.
It is also important to understand test results correctly. Genetic counselling and discussions with an oncology specialist can help women understand what their results mean and what they do not mean.
Ultimately, genetic and genomic testing is not about predicting the future with certainty. It is about giving patients and doctors more information to make better-informed decisions.
As cancer care moves towards greater personalisation, the freedom to know your risk can become a powerful part of taking control of your health—helping women move from fear and uncertainty towards awareness, informed choices and personalised care.

World Mosquito Day, observed on August 20, raises awareness about mosquito-borne diseases such as dengue, malaria, Zika, yellow fever, and chikungunya and the health risks they pose.
Among these diseases, dengue remains a major public health concern, affecting people across regions worldwide throughout the year.

Dengue is typically associated with high fever, joint pain, and low platelet counts. However, severe dengue can affect the kidneys and lead to acute kidney injury (AKI).
Speaking to HealthandMe, nephrologists said kidney problems may not always cause symptoms early on, making monitoring particularly important in severe dengue.
Dr. Anupam Roy, Additional Director - Nephrology and Kidney Transplant, Aakash Healthcare Multi-Speciality Hospital, Dwarka, said that recovering from dengue requires careful fluid management, particularly in severe cases.
It is because the kidneys regulate fluids and electrolytes, and changes in circulation caused by dengue can temporarily disrupt their function.
Fever, vomiting, and poor fluid intake can cause dehydration, while severe dengue can cause plasma leakage. Both too little and too much fluid can create problems, making medical supervision important. In hospital, healthcare professionals monitor urine output and signs of dehydration, particularly in patients with complications or underlying health conditions.
After the acute phase, patients should gradually resume eating and drinking according to medical advice. Excessive fluid intake and self-medication should be avoided, particularly when medicines could place additional stress on the kidneys.
“So, it is the quantity issue that must be tackled,” Dr. Roy said.
According to Dr. Manoj Arora, Consultant Nephrologist, NephroPlus, a network of dialysis centers, warning signs include:
Some symptoms can overlap with severe dengue, including continuous vomiting, severe stomach pain, and bleeding.
Kidney injury is more likely in people with severe dengue or shock. Older people and those with diabetes, hypertension, obesity, or existing kidney problems may also face higher risk.
Seek medical attention for a drastic reduction in urine, new swelling, blood in the urine, worsening breathlessness, confusion, or continuous vomiting.
In hospitalized patients, monitoring is important when creatinine rises, electrolyte levels fluctuate — particularly potassium — or urine output continues to change.
Early recognition and appropriate management are key. Doctors may monitor:
Do not self-medicate or increase fluid intake without medical advice, particularly during severe dengue.
Reducing mosquito exposure and preventing mosquito breeding can help lower the risk of dengue.

Are you someone who can spend hours scrolling through short videos on Instagram, YouTube or TikTok? A new study suggests that watching preferred short videos may temporarily quiet brain regions involved in self-control and monitoring, offering a possible clue to why it can be so hard to stop.
Short Videos May Quiet Brain’s Self-Control Network
The research, published in the journal NeuroImage, found that watching preferred short videos may temporarily suppress activity in parts of the brain involved in cognitive control. This effect may also be linked to levels of the brain chemical glutamate.
The study focused on the dorsal anterior cingulate cortex (dACC) and dorsolateral prefrontal cortex (dlPFC). Both are key regions of the cognitive control network, which becomes active during tasks that require mental effort, attention and self-regulation.
Researchers from Zhejiang University in China found that both the dACC and dlPFC showed significant deactivation when participants watched preferred videos to completion, compared with less-preferred videos that were stopped early.
The liked videos significantly reduced activity in both brain regions linked to cognitive control. When participants watched videos they chose to continue, activity in the dACC and dlPFC fell below normal resting levels.
However, disliked videos showed a different pattern. Activity in the dACC remained close to normal, while the dlPFC was still suppressed. Meanwhile, the visual cortex remained active during both types of videos, suggesting the changes were linked to the viewing experience rather than simply looking at a screen.
The small study of 56 participants also examined whether resting levels of two important brain chemicals could help explain differences in how participants’ cognitive control networks responded during short-video viewing.
Glutamate is the brain’s main excitatory neurotransmitter, helping increase neural activity. Gamma-aminobutyric acid (GABA) is the brain’s main inhibitory neurotransmitter, helping reduce or regulate neural activity.
The researchers found that resting-state glutamate levels in the dACC were associated with the extent of brain deactivation. Higher glutamate concentrations were linked to less suppression of activity in both the dACC and dlPFC.
Functional connectivity between the dACC and dlPFC also increased during video viewing, particularly when participants watched their preferred videos.
The researchers said the findings provide new evidence that immersive viewing of preferred short videos can deactivate the cognitive control network and that individual differences in this response may be linked to glutamate metabolism.
They suggested that the findings could help improve understanding of how digital media consumption interacts with neurochemical processes involved in self-regulation and may offer insights into the neural mechanisms behind excessive short-video use.
The study, however. does not establish that short-video viewing directly causes a loss of self-control or addictive behavior.
Previous research has linked excessive short-video use with changes in attention, focus and mental well-being.
Studies in Nature Communications and research from the American Psychological Association suggest that highly stimulating, rapidly changing content may encourage constant novelty-seeking and make sustained attention more difficult.
Potential effects include:
Short videos are not inherently harmful, but excessive or compulsive scrolling can become a concern when it interferes with sleep, work, studies or daily life.
