Semaglutide, a well-known drug for diabetes and weight loss, commonly referred to as Ozempic, has been found to help patients with peripheral artery disease (PAD) walk longer distances. PAD is a circulatory condition where narrowed arteries reduce blood flow to the limbs due to plaque buildup. This condition is particularly common among individuals with diabetes.
A study published in The Lancet demonstrated that administering 1 mg of semaglutide to adults with type 2 diabetes and symptomatic PAD led to a 13% increase in their walking distance compared to those given a placebo. The drug was also associated with an improvement in ankle-brachial indices, a key test that compares blood pressure in the ankle to that in the arm, assessing blood flow in the lower limbs. The results of the STRIDE trial were presented at the American College of Cardiology Annual Meeting on March 29. The research was funded by Novo Nordisk, the manufacturer of Ozempic.
The significance of this study lies in its demonstration of semaglutide's multifaceted protective effects beyond just improving blood sugar levels and aiding weight loss. Previous findings have already established its role in reducing the risk of cardiovascular events, benefiting kidney health, and even helping lower certain addictive behaviors.
Understanding Peripheral Artery Disease (PAD)PAD occurs when arteries narrow, restricting blood flow to the arms and legs. It is one of the most serious complications of diabetes and a leading cause of disability and amputation. More than 230 million people worldwide are affected by PAD, and there are currently no medical treatments available that can prevent or slow down its complications in diabetics.
Experts emphasize that PAD is a persistent and highly debilitating disease for which no current therapies exist. Patients suffering from PAD often experience severe limitations in their ability to function and walk without pain. As the condition progresses, some individuals may require interventions such as revascularization surgery, which aims to restore blood supply to the legs. In extreme cases, limb amputation may become necessary.
Medical professionals point out that functional impairment in individuals with PAD is often overlooked in its early stages despite the severe disability it causes. The findings of the STRIDE trial are particularly promising as they indicate that semaglutide’s benefits on maximum walking distance were noticeable at 26 weeks and continued to improve up to 52 weeks without reaching a plateau. This suggests that semaglutide could be a viable long-term therapy option for PAD patients.
Experts further highlight that amputation is one of the most feared complications of diabetes and is significantly more common in diabetic individuals than in those without the condition. The findings of this study offer a ray of hope in addressing this pressing issue.
Following the trial’s promising results, Novo Nordisk has submitted a label extension application for Ozempic to the US Food and Drug Administration (FDA). If approved, this could mark a major breakthrough in the treatment of PAD, potentially offering a new medical option for millions affected by the disease.
Hormonal changes during menopause can significantly increase Alzheimer's disease (AD) risk in women, according to Dr Lisa Mosconi, a neuroscientist and women’s brain health specialist.
In a new The Journal of Clinical Investigation review, the renowned AD expert noted that menopause can change brain biology and metabolism and may contribute to amyloid plaques and tau tangles, which are key biological markers of AD.
Alzheimer disease is the most common cause of dementia, affecting over 55 million individuals worldwide, with projections exceeding 150 million by 2050 . Out of the reported cases, nearly two-third are made up of women, with the majority being postmenopausal women
Estrogen protects the brain by lowering inflammation, increasing neuronal survivals supporting non-amyloidogenic processing, and reducing amyloid-beta-related neurotoxicity, all of which are factors contributing to the development of AD.
However, when estrogen levels drop during menopause and follicle-stimulating hormone (FSH) and luteinizing hormone (LH) rise, the brain becomes more likely to develop AD-related damage.
Previous research has also shown that early menopause, especially before age 45, is linked with increased risk of dementia and the removing the ovaries before natural menopause could increase long-term dementia risk, with the greatest excess risk seen at younger ages, especially before 45.

Alzheimer's disease is one of the most common forms of dementia and mostly affects adults over the age of 65.
About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.
Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.
Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.
Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.
While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.
Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.
There is no cure for this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.
The US Food and Drug Administration has approved the use of a blood test which can help diagnose Alzheimer’s disease in adults aged 55 and above.
The blood test, known as Lumipulse, can detect amyloid plaques associated with Alzheimer’s disease and has proven to be a “less invasive option” that “reduces reliance on PET scans and increases diagnosis accessibility.”
FDA Commissioner Martin A. Makary said of the landmark decision, "Alzheimer’s disease impacts too many people, more than breast cancer and prostate cancer combined.
"Knowing that 10 percent of people aged 65 and older have Alzheimer's, and that by 2050 that number is expected to double, I am hopeful that new medical products such as this one will help patients."
It remains unclear when this test will be available for commercial use across the world.

While GLP-1 drugs like Ozempic are popular for weight loss, a new study published today in The Lancet Psychiatry journal showed that it can also help tackle the burden of depression, anxiety, and self-harm in high-risk diabetic patients.
The GLP-1 drugs, with ingredients such as semaglutide and liraglutide, were found to effectively reduce the risk of these mental health conditions in patients already taking the medications to manage their diabetes or obesity.

The study found that these medications were linked to
The study comes as people with diabetes are known to have a higher risk of depression (2-3 times), anxiety (20 percent), and suicide than the general population.
“Our findings suggest that GLP-1 drugs, particularly semaglutide, might contribute to better mental health in people with diabetes and obesity,” said Jari Tiihonen, specialist physician and professor at the Centre for Psychiatry Research, Karolinska Institutet, Sweden.
Calling the results "observational", Tiihonen urged the need for controlled clinical trials to confirm the findings.

The researchers followed more than 95,000 participants diagnosed with depression or anxiety and were prescribed various antidiabetic medications through Swedish national registers between 2009 and 2022. Of the patients, 22,480 had used GLP-1 drugs.
Semaglutide, the main ingredient in Ozempic, showed the highest benefits against the mental health conditions. Semaglutide led to a:
On the other hand, liraglutide, sold under the brand names Victoza (for type 2 diabetes) and Saxenda (for chronic weight management), was linked to an 18 percent lower risk of worsening mental health.
Other GLP-1 medications, including exenatide and dulaglutide, did not show the same benefit.

A recent study, published by researchers at the Washington University School of Medicine in St Louis, reported that Ozempic could prevent substance use disorder and could also treat it.
Not just the lack of will to eat food, but some people have actually reported a lack of interest in alcohol or nicotine consumption.
Previously, observational studies have also shown how it could lower the risk of alcohol and cannabis use disorders, opioid overdose, and alcohol related hospitalization.
The findings published in The BMJ showed that people taking GLP-1 drugs had a 14 percent lower risk of developing any substance use disorder.

Remedies such as the consumption of warm water, fennel seeds, ginger tea, and the intake of probiotics in the form of curd may offer temporary relief. However, it is important to note that these might offer temporary relief and might not be effective if the symptoms of digestive discomfort are recurring.
Digestive discomforts that recur frequently should not be taken lightly. Frequent occurrences of digestive discomforts such as bloating and constipation might sometimes be symptoms of an underlying condition.
Therefore, if the symptoms of digestive discomfort last for weeks and if the symptoms also include the presence of any of the aforementioned symptoms of digestive discomfort, it might be important to consult a doctor.
The relationship between gut health and wellbeing is also well noted. Among the lifestyle modifications that may be implemented for improved digestive health is a healthy and balanced diet, exercising regularly, adequate intake of water, stress levels, and eating at regular times.
It is a normal occurrence for people to experience bloating and gas at some point in their lives. However, if discomfort in the digestive system is a frequent occurrence, it may be a wake-up call from the body that something is amiss and deserves attention. Heeding such a call and making lifestyle modifications may work wonders for the gut.
