Fasting may reset your body, but can it reset your mind? The new trend of dopamine fasting claims it can. And wait, there's more. This trend also works against dopamine resistance, implying that things that did not make you happier before will now do. You see, dopamine is a part of the brain's reward system and plays an important role in your pleasure reception. While this neurotransmitter is not directly linked to an individual's happiness, it triggers feelings of satisfaction, motivation and pleasure.

However, a person can also reach a stage of dopamine resistance if they continue to indulge in activities that trigger its frequent or constant release. In this case, the individual stops feeling the impact of this neurotransmitter and thus, does feel good or happy.

So does dopamine fasting work?

Dopamine fasting is a practice where individuals limit their exposure to activities or stimuli that typically provide a surge of dopamine. The idea behind dopamine fasting is to reset or recalibrate the brain's reward system. This is usually done by abstaining from gratifying things or experiences like social media, junk food, and even sex. Proponents of dopamine fasting argue that continual overstimulation from digital devices, social media, and easily accessible indulgences has numbed our brain's reward pathways. By regularly denying ourselves these dopamine triggers, the idea claims, we might restore our ability to acquire fulfilment from life's basic pleasures.

How Does Dopamine Imbalance Affect Your Mental Health?

Having low levels of dopamine can make you less motivated and excited about things. In Parkinson's disease, there is not enough dopamine in the areas of the brain important for movement. This leads to problems with muscle stiffness and movements such as walking.

The symptoms of a dopamine imbalance depend on what is causing the problem. They include physical symptoms such as:

• muscle cramps, spasms or stiffness
• digestion problems, such as constipation or reflux
• pneumonia
• trouble sleeping
• moving or speaking more slowly than usual

• feeling tired and unmotivated, or sad and lacking hope
• having low libido (sex drive)
• hallucinations (experiencing something that's not real)

How Can I Adjust My Dopamine Levels?

Adjusting dopamine levels is complicated, as it is involved in many different roles in the brain. Your doctor won't measure your dopamine levels directly, and there is no simple test to measure it. Your symptoms will be the clues that tell your doctor if you have too much or not enough dopamine. They will then prescribe medicines to adjust your dopamine level, based on your symptoms, and make adjustments based on how your body responds and how you feel.

A pharmacist has warned that people taking certain long-term medications should stay alert to subtle symptoms such as numbness, tingling, and an unusually red or sore tongue. According to Superdrug Pharmacy Superintendent Niamh McMillan, as per Mirror, the signs are often easy to dismiss and may quietly develop over time in people with low vitamin B12 levels.

Pharmacist Warns Certain Medicines May Trigger Overlooked Vitamin B12 Symptoms

McMillan explained that vitamin B12 plays a vital role in keeping nerves and blood cells healthy. A shortage can build up slowly, which means early symptoms are often brushed aside or mistaken for everyday fatigue.

She said common warning signs include persistent tiredness or weakness, breathlessness, headaches, dizziness, pale skin, and a sore or red tongue. Some people may also notice pins and needles or numbness in their hands or feet, memory lapses, trouble focusing, or changes in mood such as feeling low or unusually irritable.

Who Is Most At Risk Of Low B12 Levels?

Vitamin B12 deficiency occurs when the body either does not get enough of the vitamin from food or struggles to absorb it properly. McMillan noted that people following vegetarian or vegan diets are at higher risk, as B12 is naturally found mainly in animal products.

Older adults are also more vulnerable, as are people with digestive conditions such as coeliac disease or Crohn’s disease. In addition, those taking certain medications may be affected, particularly long-term acid-reducing drugs such as proton pump inhibitors or diabetes medication like metformin.

Dietary Sources That Help Maintain B12 Levels

To reduce the risk of deficiency, McMillan advised including reliable dietary sources of vitamin B12 wherever possible. Foods naturally rich in the vitamin include meat, fish, eggs, milk, cheese, and yoghurt.

For people who avoid animal products, fortified foods such as some breakfast cereals and plant-based milks can help support intake. In some cases, supplements may also be useful, especially when diet alone is not enough or absorption is impaired.

When To Seek Medical Advice?

McMillan stressed that anyone experiencing symptoms or falling into a higher-risk group should speak to a healthcare professional. A simple blood test can measure B12 levels, and early treatment can help prevent lasting nerve damage or other complications.

She added that Superdrug Health Clinics offer a Vitamin B12 Injection Service at selected UK locations, following clinical assessment or confirmation of deficiency.

How Medications Can Interfere With Vitamin B12?

Several commonly prescribed medications can affect how the body absorbs or uses vitamin B12. This often happens because the drugs alter conditions in the stomach or gut, making it harder for B12 to be released from food or absorbed into the bloodstream.

Medications Linked to Vitamin B12 Deficiency

The most frequently associated medications include:

• Proton Pump Inhibitors (PPIs): such as omeprazole, esomeprazole, and lansoprazole
• H2 Blockers: including famotidine and cimetidine
• Metformin
• Oral contraceptives, although experts continue to debate whether these cause a true deficiency
• Colchicine, used to treat gout and known to damage the intestinal lining
• Anticonvulsants, including drugs like phenytoin and phenobarbital, which can affect B-vitamin metabolism
• Nitrous oxide, commonly known as laughing gas, which can rapidly inactivate existing B12 in the body
• Antibiotics, particularly long-term use of chloramphenicol or neomycin, which can disrupt gut bacteria involved in B12 processing

What To Do If You Take These Medications Long Term?

Experts advise people on these medicines not to stop treatment without medical guidance. Instead, they recommend staying alert for symptoms such as fatigue, tingling or numbness in the hands or feet, brain fog, or a sore, red tongue.

Getting tested is also key. A straightforward blood test can confirm B12 levels, and many doctors now suggest regular screening for patients who take metformin or proton pump inhibitors over extended periods.

It can feel overwhelming to understand the wide range of conditions neurologists deal with. Their work spans cerebrovascular problems such as stroke and carotid artery disease, seizure disorders, and progressive illnesses like Alzheimer’s disease and frontotemporal dementia. They also treat headaches and facial pain, movement disorders including Parkinson’s, muscle conditions, sleep disorders such as narcolepsy, and many other issues.

“If there’s a nerve somewhere, a neurologist could get involved,” explains Dr. Andrew Dorsch, division chief for general neurology at Rush University System for Health and a specialist in neurologic rehabilitation. “Nerves run through the entire body. That means there are countless ways the nervous system can be affected, and figuring out the cause often requires real detective work.” He notes that many people dismiss neurological symptoms for years, blaming them on ageing or assuming they will pass. That delay can be costly.

What Are Neurological Symptoms?

Neurological symptoms are warning signs that something may be affecting the brain, spinal cord, or nerves. They can look very different from person to person. Some experience headaches, changes in vision, speech, or hearing, or sensations like numbness and tingling.

Others notice tremors, weakness, poor balance, or trouble coordinating movements. Cognitive changes such as memory lapses, confusion, seizures, sleep problems, and intense pain can also fall under this category. These symptoms happen when nerve signals are disrupted, interfering with sensation, movement, thinking, and even consciousness, according to the Cleveland Clinic.

Neurological Symptoms That Can Become Life-Threatening

According to TIME, four neurologists shared the symptoms that should never be brushed aside, along with what they could mean.

Double Vision In One Eye

Double vision affecting one eye is a symptom many people underestimate. It can stem from a range of serious conditions, including multiple sclerosis, stroke, aneurysm, myasthenia gravis, brain tumours, or infections of the brain, says Dr. Luis Cruz-Saavedra, a neurologist at Memorial Hermann Health System.

So when does it require action? “Right away,” he says. “Sudden double vision is a reason to go straight to the emergency room.” Doctors will assess vital signs, look for signs of stroke, examine the eyes and nervous system, and may recommend imaging tests such as a CT scan or brain MRI.

Weakness In One Hand Or Leg

Have you noticed one leg dragging when you walk, or found yourself limping without a clear reason? Maybe holding a cup or writing with your usual hand has become difficult. If so, it is time to see a doctor.

“I’m always struck by how many people downplay weakness on one side of the body,” Cruz-Saavedra says, noting this is far from a good thing. “Patients often come in months after it starts. Many assume it’s a pinched nerve, but it could signal a stroke, a brain tumour, multiple sclerosis, or inflammation in the brain.” During evaluation, neurologists assess muscle strength, reflexes, coordination, and walking patterns to narrow down the cause.

Transient Unresponsiveness

Some neurological conditions cause brief moments where a person seems to switch off, then quickly returns to normal without remembering what happened. These episodes are often linked to temporal lobe seizures, which affect brain areas involved in memory and emotional processing, Cruz-Saavedra explains.

Problems With Speech

Stroke remains one of the leading causes of death in the United States, yet many people fail to recognize its signs and delay seeking help. “I hear stories all the time where someone has stroke symptoms and decides to lie down and wait it out,” says Dr. Enrique Leira, director of the division of cerebrovascular diseases at the University of Iowa.

Stroke symptoms usually come on suddenly and involve a loss of function. Speech changes are a common example. A person may slur words, speak unusually slowly, struggle to find the right words, or have trouble understanding others. In such cases, immediate medical attention is essential, Leira stresses.

Sudden Headache During Physical Effort

Headaches can be tricky for neurologists because there are so many possible causes, many of them harmless. Still, certain types raise red flags. A headache that is extremely intense and appears out of nowhere, rather than building gradually, deserves attention. If it strikes during physical exertion, that concern increases.

“If it’s severe, sudden, and linked to effort, it needs to be checked right away,” Leira says, as it could point to something serious like a stroke.

Numb Feet And Fingers

When patients report numbness, it most often affects their fingers or toes. “That usually means the nerves aren’t sending signals back to the brain properly,” Dorsch explains. “The nerve may be temporarily stunned, or in some cases, permanently damaged.” This differs from tingling, which tends to suggest irritation rather than loss of signal.

The first step is a thorough evaluation to identify which nerves are involved and why. Diabetes is a common cause, but not the only one. Genetic disorders or immune conditions that attack nerves can also be responsible, Dorsch says.

A Sense Of Déjà Vu

Almost everyone experiences déjà vu now and then. But frequent episodes are a different matter. “If it’s happening regularly, it’s worth getting evaluated,” Dorsch advises. Repeated déjà vu can be an early sign of temporal lobe seizures. He recalls treating a patient who experienced these episodes weekly or every few weeks, far more often than is typical.

Difficulty Getting Out Of A Chair On A Regular Basis

With age, stiffness and slower movement are common. Still, certain difficulties stand out. If standing up from a chair becomes a recurring struggle, a medical check-up is important.

“It could be joint-related, but we also need to rule out problems with the muscles, nerves, or spinal cord,” Dorsch says. Conditions such as Parkinson’s disease or amyotrophic lateral sclerosis (ALS) may be involved. “That’s not something I’d want anyone in my family to ignore.”

Changes In Voice

Neurologists watch closely for changes in how someone speaks. One example is hypophonic speech, where the voice becomes unusually soft or breathy, which can be a sign of Parkinson’s disease, says Dr. Alexandru Olaru, a neurologist at University of Maryland St. Joseph Medical Center. Slurred speech, on the other hand, may point to a stroke.

Another concerning sign is wet dysarthria, when speech sounds gurgly, often due to saliva or mucus pooling at the back of the throat. “Muscle loss in that area makes it harder to manage saliva,” Olaru explains. Common causes include Parkinson’s disease, ALS, and multiple sclerosis.

Persistent Muscle Twitches

Occasional muscle twitching is normal. It can happen anywhere in the body and may even be visible under the skin as small ripples. “You can sometimes feel it if you place your hand over the muscle,” Olaru says. Persistent or widespread twitching, however, may warrant further evaluation.

Paranoia

Sudden shifts in behaviour or personality can signal neurological disease. Conditions such as autoimmune encephalitis, frontotemporal dementia, or other cognitive disorders may present this way. One frequent example is new-onset paranoia. A person might believe they are being targeted, betrayed, or plotted against, even when there is no logical basis, Cruz-Saavedra says.

Neurologists also take note when a typically reserved person becomes unusually talkative or disinhibited. “Some people may develop hypersexual behaviour or make inappropriate remarks,” he adds. Others may change in the opposite direction, becoming withdrawn and quiet. Dementia can also show up as new obsessive behaviours or hoarding, Cruz-Saavedra notes.

Been wondering what are Ozempic burps and how the drug works inside your body?

In a podcast episode of The Diary Of A CEO, insulin resistance expert Dr Benjamin Bikman explains how the blockbuster GLP-1 drug can alter the digestion process in your body to reduce weight.

Dr Bikman, a Professor of Cell Biology and Physiology at Brigham Young University in Utah explained: "GLP-1 is primarily a satiety hormone. It'll tell the brain that we're done eating and it will slow down the intestines significantly."

Ozempic (semaglutide) is a prescription injectable GLP-1 medication primarily approved for adults with Type 2 diabetes to manage blood sugar levels. However, the drug has gained immense popularity among those trying to lose weight as it can reduce hunger and help people feel full for longer, which forces the body to burn fat deposits to stay functional.

In clinical trials, people with obesity using semaglutide have shown to lose an average of about 15% of their body weight over 68 weeks. Most people begin to see noticeable results within 8 to 12 weeks of taking the drug.

The official price in India for a once-weekly Ozempic injection pen ranges from approximately ₹8,800 for the 0.25 mg dose to around ₹11,175 for the 1 mg dose per month. Insurance coverage is generally inconsistent for weight loss indications.

How Does Ozempic Change Your Digestion?

According to Dr Bikman, ingested food sits in the stomach and intestines for about six hours on average for digestion. However, when the body receives GLP-1 hormones from injections, the body will considerably slow down the digestion process and food can stay in the body for about 24 hours.

"If we injected ourselves with a GLP-1 drug, which puts an artificial amount of GLP-1 in our body, boom, we shoot it in. Then it would it slows down people's intestines so much that they'll have food sitting in there for 24 hours," he said during the episode.

Experts have previously noted that slowing down the digestion process on purpose using drugs is unhealthy and risky unless done under strict medical supervision to treat a specific condition (such as chronic diarrhea or dumping syndrome as it can lead to gastroparesis.

Gastroparesis is a condition that occurs when the stomach muscles become weak and slow, failing to move food into the small intestine which can reduce nutrient absorption in the body and severe constipation. It can also form a hard mass called a bezoar, which can cause blockages and may require surgery.

What Are Ozempic Burps?

"So, one of the things people talk about is what's called Ozempic burps where they just have this kind of belching bubbling gas because the food is sitting in the stomach for way longer than it's supposed to.

"So, no surprise the people are less interested in food. GLP-1 tells the brain they don't need to eat as much and slows down the intestines," Dr Bikman noted.

Can You Regain Your Ozempic Weight?

Yes. A new BMJ study has found that people who stop using weight-loss medications can regain weight and return their original size within two years.

Researchers have found that those who lose weight using blockbuster GLP-1 drugs such as Ozempic could regain about 0.4kg every month after quitting these treatments. In contrast, those who lost weight through exercise, diet and other factors only gained 0.1kg.
