We've all been there, you use the toilet, try to stand up, and suddenly your legs go numb. That odd pins-and-needles feeling can be surprising and uncomfortable. Though it might feel like a small inconvenience, it does have a scientific explanation. The numbness, also called transient paresthesia, happens when pressure blocks blood flow or presses on nerves in your lower extremities. It is normally harmless, but frequent occurrences can be signs of underlying health issues or poor toilet habits that must be addressed.
That weird numbness you experience after going to the bathroom is typically just a temporary annoyance, most often due to bad posture, straining, or sitting for an extended period. But if the numbness continues or gets worse, it is important to get medical guidance to make sure there are no underlying health issues. We discovered the top three reasons that could be responsible for this tingling and how can you avoid it? Let's dissect.
Struggling to push during a bowel movement can put excessive pressure on your abdomen and spine. This increased pressure can shift spinal discs, pressing against nerves that extend into your legs and feet. The result? A temporary loss of sensation, tingling, or weakness in your lower limbs.
Straining usually results from constipation, which in turn can be caused by a low-fiber diet, dehydration, or inactivity. If you notice that you're straining frequently, perhaps it's time to change your eating and drinking habits to help move your bowels more easily.
The way you sit on the toilet can also be a cause of that numbness in your legs. Most people are prone to hunching over when they are using their phones, reading, or just focusing too intensely. But this position can compress nerves and blood vessels in your pelvis, causing tingling or numbness.
When you sit slumped forward, you cut off blood supply to the lower half of your body, compressing nerves that travel from your pelvis to your toes. That's why the numbness will often radiate past your thighs and into your toes.
The more time you spend sitting on the toilet, the higher your chance of getting numb legs. Protracted sitting continually puts pressure on the nerves within your lower limbs, slowing blood flow and leaving you with the familiar pins-and-needles feeling.
If you habitually stay on the toilet for a long time, either from digestive problems or distractions such as browsing your phone, you may find that there is more numbness over the course of time. If constipation is leaving you on the toilet longer than normal, diet changes can calm your system.
Although periodic tingling is not a health issue, recurring numbness is a problem that needs to be addressed. Below are some professional-recommended ways of preventing it:
Being seated with your knees higher than your hips can make all the difference. Sitting this way enables your colon to unwind, facilitating smooth bowel movements while minimizing pressure on the lower parts of your body.
Don't slouch, as this squishes nerves and blood vessels, making numbness more likely. If necessary, lean your back against the toilet tank or wall to keep your posture good.
Specialists recommend five to ten minutes of toilet time per visit. If you are straining, stand up, walk around, and try later. Forcing the bowel movement can cause more damage than benefit, putting greater pressure on your spine and worsening numbness.
If constipation is a chronic problem, being hydrated and consuming fiber foods such as fruits, vegetables, and whole grains can get your digestive system back in working order.
Raising your feet using a toilet stool may position your body for a more natural and strain-free bowel movement. A squatting position keeps the rectal canal open, minimizing the need to push and reducing the risk of leg numbness.
Hard toilet seats can restrict circulation in your lower body, increasing the risk of numbness. A cushioned or padded toilet seat can provide better support, improving blood flow to the legs and feet while reducing pressure on the pelvis.
While it's normal to have some numbness in your legs from time to time when sitting on the toilet, ongoing tingling or numbness in your lower extremities may be a symptom of an underlying medical condition. If you find yourself experiencing:
It's best to see a healthcare expert to exclude conditions such as nerve compression, circulatory disorder, or spinal condition.

Vaccinated for human papillomavirus (HPV)? Now, take that Pap smear test. This is the most common advice women hear to prevent the risk of cervical cancer that annually causes around 6,60,000 new cases and around 350,000 deaths worldwide.
However, it's easier said than done for most of the fairer sex.
A Pap smear is typically a gynecological examination where a speculum is inserted to collect cells from the cervix.
Although the procedure is brief and generally safe, the discomfort discourages many from getting screened. Fear of pain, anxiety of the results, form the common psychological barriers worldwide, and is followed by shame, cultural attitudes, and concerns with male clinicians.
A study in Iran, published in the BMJ Open journal in January 2024, showed that psychological stress, cultural issues, and fear, along with limited information and health services, were the biggest hindrances to getting Pap tests.
Another research published in the BMC Women's Health in December 2022, focusing on Africa, Asia, and South America, reported that many women avoided or delayed Pap smears because they are afraid the procedure will hurt. Many also reported being embarrassed about the pelvic exam or fear of having a stranger see their private areas. Some also worried that the test could damage the uterus.
A Pap Smear test, however, is proven to be safe and is recommended for every woman above the age of 21 years.
“A Pap smear is a rapid, safe, and painless screening procedure that detects irregular cellular changes well before they become malignant. The ability to treat at this pre-cancerous stage of disease provides an excellent outcome,” Dr. Tirathram Kaushik, Senior Consultant GI, HPB, Gastrointestinal & Thoracic Oncology and Robotic Surgery, HCG Cancer Centre, Borivali, told HealthandMe.
A 2025 study, published in the Journal of Contemporary Clinical Practice, showed that pap smears are excellent at ruling out precancerous risks. It also remains a valuable screening tool where molecular testing is limited.
There are many myths about Pap smears that make people anxious or avoid screening. Let’s clear up the most common ones:
The Pap smear procedure, which takes only a few minutes, is often described as uncomfortable. While some feel like a quick pinch, others experience slight discomfort or spotting. Severe pain is not considered normal.
“From an oncology perspective, this myth results in a delay in diagnosis. Cervical cancer often occurs silently in its early stages, without any noticeable symptoms,” Kaushik said.
While individuals may feel completely well, they still have abnormal cells developing silently. As a result, regular Pap smear screening is important because it detects these changes early -- before they turn into cervical cancer.
“The HPV infection and subsequent changes that lead to cervical cancer happen slowly over many years. HPV infection is also very common, and one in two women is likely to get infected. Regular screening by a Pap smear will help to catch infection early before it can convert into cancer,” Dr. Deepak Jha, Chief - Breast Surgery & Sr. Consultant Surgical Oncology, Artemis Hospitals, told HealthandMe.
“HPV doesn’t need penetrative sex for infection. It can be transferred if there is any contact of bodily fluid. It’s always safe to test and be assured rather than repent later,” Dr. Jha said.
“Even if HPV is detected, it usually indicates a pre-cancerous stage that is highly treatable,” Dr. Parminder Kaur, Consultant Gynecologic Oncologist at CK Birla Hospital, Delhi, told HealthandMe.
Moreover, a Pap smear only screens for cervical cancer; it can’t detect other gynecological cancers such as cervical, ovarian, uterine (endometrial), vaginal, and vulvar cancers. So, screening and appropriate tests for those will be required, irrespective of the Pap smear.
Irrespective of vaccinated status, a woman should go for regular screening between the ages of 25 and 79. Also, if a woman already had HPV exposure before being vaccinated, she would not benefit, the experts said.
“Screening is not just a routine procedure - it is a preventive measure. In the treatment of cancer, early detection alters the disease course, whereas waiting for symptoms to develop means the disease is likely to be already advanced,” Dr. Kaushik said.
Dr Kaur called for more awareness and stated that open discussion are key to help more women take the important screening test.
The United States Preventive Services Task Force (USPSTF) and the American Cancer Society (ACS) recommend getting your first Pap test at age 21, followed by Pap testing every 3 years. Even if you are sexually active, you do not need a Pap test before age 21.
In women older than 65, you don't need to be screened anymore if:

Are you still experiencing brain fog, fatigue, and mood changes even after years of a mild COVID-19 infection? A new study showed that the SARS-CoV-2 virus, behind the COVID infection, can cause persistent brain inflammation and lung injury, according to a study.
Researchers from Tulane University, in Louisiana, US found that the brain inflammation lasts long even after the virus was no longer detectable.
Their study, published in Frontiers in Immunology, can answer why long COVID often includes neurological symptoms such as brain fog, fatigue, and mood changes.
"Long-term effects on the brain were unique to SARS-CoV-2. That distinction is critical to understanding long COVID," said lead author Dr. Xuebin Qin, professor of microbiology and immunology at the Tulane National Biomedical Research Center. Qin also mentioned "lasting lung injury" among COVID patients.
In a mouse model, the team found that immune cells in the lungs failed to fully stand down and also spiked the buildup of collagen -- a protein associated with scarring.
The changes stiffened lung tissue, making breathing feel more labored -- a possible answer to breathlessness faced by COVID survivors.
Further, the researchers also noted no repair to the injury, suggesting the virus may interfere with the lung's natural healing process.
On the other hand, in the brain, the mice with COVID showed signs of persistent brain inflammation weeks later. The team also reported tiny areas of bleeding.
Conducting a gene expression analysis, the team found ongoing inflammatory signaling and disruption of pathways involved in serotonin and dopamine regulation -- brain functions linked to mood, cognition, and energy levels.
Long COVID is a collection of symptoms that last three months or longer after your first COVID symptoms. They include fatigue, brain fog, headaches, breathlessness, altered sense of smell or taste, headaches, and more.
While many of the Long conditions remain to be fully recognized, some people have more than one symptom.
As per recent data from the World Health Organization, more than 43,000 new cases have been reported from 61 countries, between January and February.
Vaccination that prevents SARS-CoV-2 infection is the most effective way to prevent long COVID.
Recently, the European Medicines Agency (EMA) recommended a marketing authorisation in the European Union (EU) for mCombriax -- a messenger RNA vaccine for protecting people aged 50 years and older against COVID-19 and seasonal influenza (flu).
Co-infection with the influenza virus and SARS-CoV-2 can result in more severe disease than would occur with either SARS-CoV-2 or influenza virus infection alone.
mCombriax works like other vaccines by preparing the body to defend itself against infection. It contains messenger RNA with instructions for making proteins found on SARS-CoV-2 and the following seasonal influenza viruses: influenza type A-H1N1, influenza type A-H3N2, and influenza type B of the Victoria lineage.

Vitamin B12 might sound like just another nutrient on a health label but it plays a major role in how your body works. The vitamin is crucial in helping the body produce red blood cells, supports your nervous system and essential for making DNA, which is the genetic material inside all your cells.
Symptoms of a Vitamin B12 deficiency often appear slowly. You may not notice them at first, or may blame them on stress, lack of sleep or a busy schedule. However, if this deficiency continues for too long, it could lead to serious health problems.
Here are three key signs to look out for:
Vitamin B12 is extremely crucial for making red blood cells who are responsible for carrying oxygen from your lungs to the rest of your body. Oxygen is what your cells need to produce energy.
Without adequate levels of B12, the body cannot produce enough healthy red blood cells, leading to a condition called anemia.
This can make you feel constantly exhausted, even after getting enough sleep. You may also feel weak, short of breath or find that everyday tasks feel harder to do than they generally are.
If the fatigue feels persistent and does not improve with rest, it is important to seek a consultation with a doctor.
Vitamin B12 is also essential for maintaining the myelin sheath, a protective covering around your nerves. You can think of it like the protective plastic that we see around electrical wires. It helps nerve signals travel quickly and correctly between your brain and the rest of your body.
When B12 levels are too low, this protective layer can become damaged and subsequently lead to nerve signals slowing down or misfiring. This may lead you to feel pins and needles, tingling or numbness in your hands and feet. Some people also experience burning sensations or difficulty with balance.
At first, it may seem minor, such as your foot ‘falling asleep’. But if these sensations happen often or without a clear reason, they should not be ignored. Long-term B12 deficiency can cause permanent nerve damage, which is why early medical consultations are important.
Your brain also depends on vitamin B12. It helps your body produce neurotransmitters, which are chemicals that allow brain cells to communicate with each other. These chemicals influence memory, focus and mood.
When B12 levels are low, communication between brain cells may not work as efficiently. You may notice difficulty concentrating, forgetfulness or a feeling of mental fog. Some people feel more irritable, anxious or unusually low in mood.
As these symptoms are common during stressful times, they are often dismissed. However, if you feel mentally different from your usual self for a long period, it is important to investigate the cause.
Vitamin B12 is mainly found in animal-based foods such as meat, fish, eggs and dairy products. People who follow vegetarian or vegan diets may need fortified foods or supplements to get enough.
Absorption is also a key factor. Vitamin B12 needs a special protein in the stomach called intrinsic factor to be absorbed properly. Certain medical conditions, medications, or aging can reduce absorption. This means that even if someone eats enough B12, their body may not absorb it efficiently.
If you experience ongoing fatigue, tingling sensations or noticeable changes in memory or mood, consult a healthcare professional. A simple blood test can measure your B12 levels.
The good news is that Vitamin B12 deficiency is usually treatable. Treatment may include dietary changes, oral supplements or, in more severe cases, injections. When identified early, most people recover well.
Vitamin B12 supports your blood, nerves and brain. A deficiency can quietly affect your energy, sensation and thinking over time.
Pay attention to persistent changes in your body. If something feels consistently wrong, it is important to seek medical advice. Early detection can prevent long-term complications and help restore your health.
