Ozempic has been a household name for the last two years. The injectable medication, which was initially designed to treat type 2 diabetes, has now been making the news for its incredible weight loss properties. It functions by doing the same thing as a natural hormone, called GLP-1 (glucagon-like peptide-1), that controls blood sugar and suppresses hunger.
But here's the surprise: your gut might already contain the secret to a similar effect—no needle in sight. A recent study says that some gut bacteria and their products can induce GLP-1 production in manners that mirror what Ozempic does, with implications of a more natural, side effect-free alternative to the drug's effects.
GLP-1 is one of the body's own hunger and blood sugar controllers. It's manufactured by specialized gut cells called enteroendocrine cells (EECs), which detect nutrients and initiate hormonal signals that retard digestion, stabilize blood sugar levels, and make you feel full.
Obese individuals tend to have fewer EECs and reduced GLP-1 activity, making it harder to control appetite. That's one of the reasons why GLP-1 receptor medications like Ozempic work so well—they substitute for what the body isn't currently making in sufficient amounts.
The question has been: how can we make the gut increase GLP-1 levels naturally, without man-made medication?
Scientists at Marshall University in West Virginia think the answer could be affirmative. Their recent study, published in the International Journal of Molecular Sciences, concluded that gut bacteria and their metabolites can persuade the gut to release more EECs—and by association, more GLP-1.
The researchers homed in on tryptophan, an amino acid perhaps most famously associated with turkey dinners. When gut microbes break down tryptophan, they produce a metabolite known as indole. That chemical, they found, behaves like a kind of stimulus for the gut, triggering a cascade that results in the creation of new GLP-1-producing cells.
The major mechanism involved is the aryl hydrocarbon receptor (AhR), a receptor that assists in the control of those cells' response to various molecules. After indole activates AhR, the gut seems to increase its level of EECs, restoring a balance of GLP-1 that can assist in regulating appetite and metabolism.
Thus far, the evidence is from rat tests and cell-cultured "mini-guts" (organoids). Both times, adding tryptophan and indole pushed the gut toward GLP-1 production. But that's still a work in progress to apply to humans.
Obesity and metabolism are mediated by a network of molecular pathways, diet, and lifestyle. What is effective in a rat's gut need not be so in ours. The researchers admit that "the molecular players and signaling pathways involved in the regulation of EEC differentiation could be different in normal and obese conditions.
Nevertheless, the science suggests a thrilling therapy: activating gut microbes, diet, and specific supplementation to push the body to produce its own appetite-controlling hormones.
Ozempic and other medications in this class are effective, but they come with trade-offs. Nausea, gastrointestinal problems, and worse side effects have occurred. They're costly, too, and, in most nations, difficult to obtain.
A biological route to GLP-1 production—through diet, supplements, or probiotics—may even provide a more secure, less expensive option. Tryptophan is already plentiful in foods such as poultry, eggs, cheese, and some seeds. If scientists can dial in the way that these foods or supplements are utilized to best maximize GLP-1 function, what they create might resemble a "natural Ozempic."
Although research is in its infancy, history provides a clue that the solution may be nearer than we imagine. Well before semaglutide injections became popular, people across the globe were consuming foods naturally in their diets to support blood sugar balance, hunger regulation, and weight health.
The Mediterranean diet—rich in olive oil, fish, legumes, and colorful plants—has long been linked to improved insulin sensitivity and lower risk of type 2 diabetes. Its balance of healthy fats, fiber, and lean proteins naturally slows digestion and helps control appetite.
In Japan, meals centered on rice, vegetables, fermented foods, and small portions have a similar effect. Fermented foods themselves can increase diversity of the gut microbiome, and in turn support GLP-1 activity indirectly.
In Okinawa, purple sweet potatoes and bitter melon have been consumed for hundreds of years. Both are high in compounds that promote gut health and can activate hormones related to GLP-1.
You don't have to transform your diet overnight. Gradual change can coax the gut along the same routes. For instance:
The Marshall University study contributes to a large and expanding area of research that investigates how the gut and its microbes affect obesity and metabolism. What comes next will be required to try these findings in human subjects, determine the ideal dose of tryptophan or indole, and establish safety in various populations.

We have all been there, done that. Reaching out to Google every time we face slight discomfort sneezing, convinced that we have some serious disease. While not every ache or tickle means an emergency, some symptoms really do need urgent attention. According to ER doctors, there are a handful of red flags you should never brush off.
Here are six warning signs you should pay attention to immediately.
We have all had heartburn after a cheesy pizza, but chest pain is not something to gamble with. Reports say crushing, pressure-like chest pain that radiates to your arm, jaw, or back is a huge red flag for a heart attack. Sometimes it comes with sweating, shortness of breath, or nausea. Even if you are young and otherwise healthy, do not assume it is just gas or stress. When in doubt, get checked out; it is always better to be told it is heartburn than to ignore a heart attack.
Sure, headaches are common, but if you suddenly feel like someone is hammering your skull with no mercy, do not tough it out. According to the reports, a sudden, severe headache, especially if it is different from your usual migraines, could signal a brain aneurysm, bleeding, or other neurological emergency. Pair that with vision changes, weakness, or slurred speech, and you should be calling for help immediately.
Running up the stairs and wheezing like a deflating balloon is one thing. But struggling to breathe at rest or without any exertion? That is a whole different story. Experts say unexplained shortness of breath could point to conditions like blood clots in the lungs, asthma attacks, pneumonia, or even heart problems. If your chest feels tight, you are gasping for air, or your lips are turning blue, it is not something to “walk off”.
If you are holding something, and suddenly it slips right out of your hand because your arm has no feeling. Or half your face feels like it is melting. These are classic stroke symptoms, and ER doctors stress that time is everything. The quicker you get treatment, the higher the chances of recovery. Remember the acronym FAST: Face drooping, Arm weakness, Speech difficulty, Time to call emergency services. Do not wait it out hoping it will pass.
A paper cut? No big deal. A deep cut that refuses to stop bleeding after 10 minutes of firm pressure? That is a medical emergency. According to the reports, that uncontrolled bleeding can mean a damaged artery or an underlying clotting disorder. If you are soaking through bandages or the blood will not stop, it is not something to ignore. Plus, losing too much blood too quickly can lead to shock and nobody wants to faint in their bathroom.
Stomach aches are often brushed off as bad food choices. But if you suddenly develop intense abdominal pain that does not go away, reports suggest it could be something much more serious, like appendicitis, gallstones, a perforated ulcer, or even an intestinal blockage. The kind of pain where you cannot stand up straight or move without wincing is not the “sleep it off” kind. Trust your gut, literally, and get checked.

As the temperature rises, the rise in tick-borne disease are also being reported. When you think about ticks, you probably think about Lyme disease or the general unease of finding one clinging to your skin.
However here’s an important fact: just because a certain tick species is found in your area doesn’t automatically mean it spreads a specific disease there. Disease transmission depends on several factors, from local ecology to host availability, not simply the presence of ticks.
Still, understanding which ticks are in your region helps you stay alert to potential health risks.
Below is a guide to the major tick species in the United States, what they look like, where they’re found, and the diseases they may carry.
As per the Centers for Disease Control and Prevention (CDC), the American dog tick is common east of the Rocky Mountains and in some western pockets. A related species, D. similis, lives west of the Rockies.
These ticks can spread tularemia and Rocky Mountain spotted fever (RMSF).

Spring and summer are peak seasons for bites, with adult females being the ones most likely to latch onto humans.
CDC notes that it was first detected in the U.S. in 2017. This invasive species has spread quickly. As of 2024, it has been reported in at least 19 states, including New York, Virginia, North Carolina, and Kentucky.
In Asia, these ticks are known to spread pathogens that can make humans and animals seriously ill. In the U.S., their disease-spreading potential is still being studied. While they are less likely to bite humans compared with native ticks, they can carry bacteria that cause Rocky Mountain spotted fever, though this hasn’t been found naturally in U.S. populations yet.
These ticks reproduce without mating, meaning a single female can produce thousands of offspring. They’ve been found on pets, livestock, wildlife, and even people, often appearing in large numbers in grassy or shrubby areas.
CDC notes that this is common across the eastern United States.

This tick is one of the most medically important in the U.S., spreading multiple diseases, including:
The risk of bites is highest in spring, summer, and fall, but adults can be active anytime winter temperatures rise above freezing. Nymphs and adult females are the main culprits when it comes to human bites.
It is truly a global traveler, this tick is found worldwide and throughout the U.S.
In certain parts of the U.S., especially the Southwest and along the U.S.-Mexico border, it can spread Rocky Mountain spotted fever.
Dogs are the preferred hosts at every stage of their life cycle, but they can also bite humans. Because of their close association with dogs, they often infest kennels, homes, and even veterinary clinics.
Primarily in the southeastern U.S., with isolated populations in other regions such as the Midwest and Southwest.
The main disease linked to this tick is Rickettsia parkeri rickettsiosis, a type of spotted fever.
Adults are most often involved in transmitting pathogens to humans.
This aggressive biter is found widely in the Northeast, South, and Midwest.
Lone star ticks are linked to several diseases and unusual health effects, including:
Adult females can be recognized by a single white dot, or “lone star”, on their back. Their bites can cause skin irritation even without infection. Nymphs and females are most likely to bite humans.
Lives in the Rocky Mountain states and parts of southwestern Canada, mostly at elevations between 4,000 and 10,500 feet.
Known carriers of Rocky Mountain spotted fever, Colorado tick fever, and tularemia.
Adult ticks are the primary stage that transmit diseases to people.
It is found along the Pacific Coast, especially in northern California.

When was the last time you tried brushing your teeth with the “wrong” hand and ended up with toothpaste on your nose? Or fumbled with your fork as though you had suddenly forgotten how to eat? As it turns out, those awkward, clumsy attempts may actually be doing your brain a massive favour.
Dr Sudhir Kumar, neurologist, explains: “Using your non-dominant hand for daily activities like brushing your teeth, eating, or opening doors can challenge your brain, encourage new neural connections, and may improve cognitive flexibility over time.”
You have probably heard that your brain is like a muscle, but have you ever thought about putting it through a workout that does not involve solving puzzles? According to Dr Kumar, “Just like muscles, your brain gets stronger with exercise. Switching hands forces your brain to adapt, stimulating regions that are usually less active.”
That means the slip-ups and slowed-down movements are not failures but signals that your brain is firing up areas it does not usually depend on.

The best thing about this brain exercise is that you do not need different tools or complicated routines. In fact, the things you do every single day are the perfect training ground. Dr Kumar suggests a few easy ways to get started:
1. “Eat or cook with your opposite hand.”
2. “Use it to operate your phone.”
3. “Write a short note.”
4. “Use it to brush teeth, comb your hair or shave.”
5. “Try simple percussion (e.g., drumming) or piano melodies with the non-dominant hand taking the lead.”
Scientists often talk about neuroplasticity, which is the brain’s ability to rewire itself. While big life changes and new learning experiences are known to boost this, tiny everyday tweaks, like stirring your tea with your left hand if you are right-handed, also count. Over time, these switches may improve focus, problem-solving skills, and adaptability.
Plus, there is something oddly satisfying about realising you have mastered a task you once struggled with. Writing a little something with your left hand may look tough at first, but give it a week and you will notice surprising progress.

Of course, do not expect your non-dominant hand to suddenly become proficient at everything you do. At first, the tasks might feel frustrating, and your movements clumsy. But that awkwardness is precisely the point; it is your brain stretching itself in new directions. Training your brain with these small hand switches works on the same principle: deliberate struggle leads to growth.
Brain health often feels like a heavy topic reserved for discussions about memory loss or ageing, but adding a dose of play makes it a whole lot lighter. Using your non-dominant hand is basically an easy game you can play with yourself, without apps, subscriptions, or brain-training gadgets.
