Diabetes is one of the chronic lifestyle conditions that most older adults fear developing, especially past the age of 40. This is when body's main source of energy or glucose is too high. However, recent cases show that diabetes may no longer be a disease of aging. While most people who are middle-aged or older adults develop Type 2 diabetes, there is in fact a rise in cases among the youth, including children.

As per the Centers for Disease Control and Prevention (CDC), US, 352,000 children and adolescents younger than age 20 years in the US are diagnosed with diabetes. Furthermore, in the UK, the number of children with type 2 diabetes have risen by more than 50%, as noted by the NCBI data.

In India too, there is a sharp rise in diabetes across all age groups, with many cases going undiagnosed until complications set in, says Dr Mayanka Lodha Seth, chief pathologist at Redcliffe Labs. " Diabetes cases are rising not just among older adults but also in children, teenagers, and youngsters in their 20s & 30s," says the doctor.

Why The Youth Must Know?

The doctor also says that more often than not, scientific terminology could be confusing, even, scary, in such a scenario, it is important to break down the scientific jargon for them. Dr Mayanka Lodha Seth does exactly that. He presents with the 'Five Must Knows' from what he calls a Diabetes Dictionary.

HbA1c: HbA1c reflects your average blood sugar levels over the past 2–3 months, showing how well your body has been managing glucose. This can be considered as your long-term report card and not just a day’s blood analysis.

Insulin Resistance: Insulin Resistance happens when your body stops responding properly to insulin; the hormone that helps use sugar for energy. So, even with enough insulin, sugar stays in your blood instead of fueling your cells, slowly raising your risk of diabetes.

Glycemic Index (GI): GI tells you how quickly a food raises your blood sugar after eating it. Foods with a low GI keep your energy steady, while high GI foods cause quick spikes and crashes in blood sugar.

Fasting Blood Sugar (FBS): Fasting blood sugar is your body's early morning status update. It reveals how effectively your body manages blood sugar after several hours of fasting.

Prediabetes: Prediabetes means your blood sugar is starting to creep up; not diabetes yet, but your body’s giving you a gentle nudge to pay attention. It’s the perfect stage to turn things around with small, healthy changes.

Why knowing these terms are necessary? The doctor says that knowing these terms will help the young patient keep a track of their sugar levels, and also to catch problems early.

Are There Ways To Manage Sugar Levels?

The doctor says yes. The doctor suggests simple steps, such as consuming low GI (≤55) foods on a regular basis, can help regulate sugar levels and prevent sudden sugar spikes. "These foods include oats, lentils, apples, milk, yogurt, green vegetables, and sweet potatoes. Additionally, high-GI foods like white bread, white rice, cornflakes, potatoes, pastries, sugary drinks,, and other junk and fried foods should be avoided. Besides regulating eating habits, simple steps such as regular exercise, brisk walking, and stress management can help control sugar levels."

Atrial fibrillation (AFib) is an irregular and often very rapid heart rhythm, also called an arrhythmia and can create blood clots in the heart, which can increase your risk of having a stroke by five times.

When a person has AFib, the normal beating in the upper chambers of the heart (the two atria) is irregular and blood doesn't flow as well as it should from the atria to the lower chambers of the heart (the two ventricles).

Common symptoms include palpitations (the feeling that your heart is racing, pounding, fluttering or like you have missed heartbeats), chest pain, finding it harder to exercise, tiredness, shortness of breath, dizziness or feeling faint. However, a more severe symptom is a stroke.

Tucked inside the heart is a tiny pouch called the left atrial appendage. When the heart beats erratically, blood can pool and sit still in this pouch instead of flowing normally and still blood tends to clot. If one of those clots breaks free and travels to the brain, it can block blood flow and cause a stroke.

But researchers have now found new technique, in which a magnetically guided liquid is injected into the heart can harden and permanently seal the left atrial appendage from the inside. Early tests in rats and pigs suggest that this method could one day lower the risk of stroke in people with atrial fibrillation.

Based on this technique, researchers inject a magnetically responsive liquid, sometimes called a magnetofluid, directly into the left atrial appendage through a catheter.

Once inside the cavity, an external magnetic field helps guide and hold the fluid in place, so it fills the entire appendage, even against the force of circulating blood.

Within minutes, the liquid reacts with water in the blood and transforms into a soft "magnetogel" that seals off the cavity. Additionally, as the material begins as a liquid, it can adapt precisely to the highly irregular shape of each patient's left atrial appendage.

The death rate from AFib as the primary or a contributing cause of death has been rising for more than two decades.

Over 454,000 people with AFib are hospitalized in the US each year, out of which 158,000 die of the cause. It is estimated that 12.1 million people in the US will have AFib in the US will have AFib by 2050.

Who Is At Risk Of Having AFib?

Risk factors for AFib include:

• Advancing age.
• High blood pressure.
• Obesity.
• European ancestry.
• Diabetes.
• Heart failure.
• Ischemic heart disease.
• Hyperthyroidism.
• Chronic kidney disease.
• Moderate to heavy alcohol use.
• Smoking.
• Enlargement of the chambers on the left side of the heart.

Treatment for AFib includes medications to control the heart's rhythm and rate, therapy to shock the heart back to a regular rhythm and procedures to block faulty heart signals.

A person with atrial fibrillation also may have a related heart rhythm disorder called atrial flutter. The treatments for AFib and atrial flutter are similar.

How To Improve Your Heart Health

Experts recommend following the below to reduce yor risk of stroke or developing AFib and maintaining heart health:

• Don't smoke or use tobacco.
• Aim for at least 150 minutes of moderate physical activity or 75 minutes of vigorous physical activity (or an equal combination of both) each week. Eat a heart-healthy diet.
• Stay at a healthy weight.
• Get quality sleep.
• Manage stress levels
• Get regular health screening tests.
• Eat a fiber, nuts and fish-rich diet
• Limit salt intake
• Reduce saturated fat intake

Orforglipron, a new daily pill, may be more effective than existing oral treatments for weight loss and blood sugar control than semaglutide, according to a recent clinical trial.

Semaglutide belongs to a group of drugs known as GLP-1 medications, known to mimic a natural hormone that helps regulate appetite, slow digestion, and control blood sugar. The drug is commonly sold under the brand names Wegovy and Ozempic.

Despite being highly effective, semaglutide usually needs to be injected and requires refrigeration, which can make it inconvenient and harder to access for some patients. Additionally, the drug also carries a high price point.

However, in a 52-week trial involving people with Type 2 Diabetes, orforglipron was found to lower average blood sugar levels more than oral semaglutide and also led to greater weight loss.

Participants taking orforglipron lost around up to eight kilograms on average, compared to about five kilograms with semaglutide. Morever, orforglipron is a once-daily pill that does not require injections or cold storage.

But the study also found that orforglipron caused more side effects, particularly digestive issues like nausea and diarrhea. Yet scientists believe it may still be a better alternative to semaglutide as its easier and cheaper to produce than peptide-based drugs like semaglutide.

They also noticed that the drug absorbed more efficiently by the body and does not require strict timing around meals, unlike current oral versions of semaglutide.

How Does Ozempic Function?

The first thing to remember here is that Ozempic is a brand-name medicine that contains semaglutide as its active ingredient. Semglutide is the synthetic version of GLP-1—a natural hormone produced in the intestines that regulates blood sugar, appetite, and digestion. Now, every time you eat, your body produces various hormones, including GLP-1. These are called Post nutrition hormones, and help you absorb the energy you just consumed.

GLP-1 travels to your pancreas, prompting it to produce insulin. It also travels to the hypothalamus in your brain, which gives you the feeling of being full or satiated. Ozempic imitates this hormone, thereby, silencing the food chatter in the brain. Interestingly, for some people this food chatter is really quiet ( people with low appetite) and for others it is an outbrurst, (people who generally binge eat.) So with Ozempic, silencing this self-talk in the brain, people tend to lose their appetite and eventually weight.

However, it is important to note that losing weight includes not just fat but muscle as well. Losing too much muscle can lead to reduced strength and a shorter life span. Notably, records show that most people who start taking them stop it at 12 weeks; therefore, it is important for some but not for others.

Does Ozempic Have Side Effects?

As reiterated by doctors and health care experts, Ozempic is a drug that is tasked to help diabetic patients manage their blood sugar levels and weight. However, recent research has shown its effectiveness in mitigating various addictions like alcohol and drugs by inhibiting hormones. But what people ignore are its side effects, which include:

• Nausea is a frequent side effect, especially when starting Ozempic or increasing the dose, and vomiting may occur along with nausea.
• Diarrhoea and abdominal discomfort also show up in people using Ozempic, but they generally resolve as your body adjusts.
• Ozempic can reduce appetite but may also lead to unintended weight loss or reduced food intake, causing discomfort for some people.
• There are certain less common, but serious side effects also, like Pancreatitis, or inflammation of the pancreas.
• This drug may also cause severe kidney issues, particularly if dehydration occurs from side effects like vomiting or diarrhoea.

People with blood type B, either positive or negative, are 28 percent more likely to develop Type 2 diabetes, according to a 2024 BMC Medicine study.

Human blood is categorized into eight main groups based on the sugars and proteins, or lack thereof, present on the surface of your red blood cells.

A, B, and AB types are based on the presence of antigens, sugar molecules that can trigger an immune response. O-type blood has no A or B antigens. Meanwhile, Rhesus (Rh) factors are proteins that determine blood compatibility and give your blood its positive or negative designation.

According to a group of Chinese researchers, who conducted a thorough umbrella review of 270 studies, the strongest link between a blood group and Type 2 diabetes was between those with a B blood group.

The researchers also didn't examine what might drive this increased risk. A 2025 study suggests that the gut microbiome may be involved; however, further investigation is needed.

However, the results do suggest that there's a real, tangible association between blood type and Type 2 diabetes – one that people can factor into how they think about their own risk.

What is Type 2 Diabetes?

Type 2 diabetes (T2D) occurs when blood sugar (glucose) remains consistently high. Normal blood sugar levels fall between 70 and 99 milligrams per deciliter (mg/dL). If undiagnosed, Type 2 diabetes often shows levels of 126 mg/dL or more.

T2D happens because the pancreas doesn’t produce enough insulin, the body can’t use insulin effectively, or a combination of both. This differs from Type 1 diabetes, which arises when the immune system attacks the pancreas, leaving the body unable to produce insulin at all.

How Common Is Type 2 Diabetes?

Type 2 diabetes is widespread. Over 37 million people in the US have diabetes (around 1 in 10), with 90–95 percent of cases being T2D. Globally, it affects roughly 6.3 percent of the population. While it’s most common in adults over 45, younger adults and even children can develop it.

Blood Sugar Range For Adults And Children With Type 2 Diabetes

The American Diabetes Association recommends the following ranges for adults with type 1 or type 2 diabetes and children with type 2 diabetes:

Recommended Blood Sugar Range

Fasting (before eating): 80 to 130 mg/dL

1 to 2 hours after meal: Lower than 180 mg/dL

Is Type 2 Diabetes Genetic?

T2D has complex causes, but genes play a significant role. If one biological parent has T2D, your lifetime risk is around 40 percent, and if both parents do, it rises to 70%. Scientists have identified over 150 DNA variations linked to T2D risk, some increase the chance of insulin resistance or reduced insulin production, while others influence obesity risk. These genetic factors interact with lifestyle and health habits to determine overall risk.

How is Type 2 Diabetes Diagnosed?

Doctors use several blood tests to confirm T2D:

• Fasting plasma glucose test: Measures blood sugar after an eight-hour fast. A result of 126 mg/dL or higher indicates diabetes.
• Random plasma glucose test: Measures blood sugar at any time without fasting. A reading of 200 mg/dL or higher signals diabetes.
• A1C test: Reflects average blood sugar over the past 2–3 months. A level of 6.5% or higher indicates diabetes.
