Most people are aware of type 1 and type 2 diabetes, but did you know there is a type 3 diabetes as well! It is a more obscure term. Although it is not an accepted medical diagnosis, type 3 diabetes has been discussed in the literature as a possible relationship between insulin resistance in the brain and Alzheimer's disease. This link has been described to help explain how metabolic disorders impact brain health, causing cognitive decline and dementia.

What is Type 3 Diabetes?

Type 3 diabetes is more of a misnomer because it should not be confused with type 3c diabetes, which relates to pancreatic dysfunction. The term "type 3 diabetes," on the other hand, has been loosely used by some scientists to analogously propose that Alzheimer's disease is strongly implicated with insulin resistance in the brain.

This concept was conceptualized by Dr. Suzanne de la Monte and Dr. Jack Wands of Brown University in the year 2008. This hypothesis postulated that Alzheimer's disease may be called type 3 diabetes for it bears many similarities with glucose metabolism disorder type 2 diabetes. Their concept arises from the basic principle that insulin is fundamental to blood sugar regulation, but it is also the case with the brain. When brain cells become insulin-resistant, they lose access to glucose, impairing their function.

Research published in the Journal of Diabetes Science and Technology supports this hypothesis by indicating that insulin resistance can be a significant contributor to the occurrence of dementia, also referred to as Alzheimer's. The symptoms of memory loss and diminished reasoning are associated with impaired glucose metabolism in the body, especially in the cerebral tissue.

Symptoms of Type 3 Diabetes

Although type 3 diabetes is not a "medical term," its symptoms correlate well with Alzheimer's diseases that are known to reduce the ability to think in an efficient manner and bring down brain health. These signs are:

- Loss of memory, especially short-term.

- Poor judgment and judgment ability

- Failure in recognizing people or places familiar once.

- Failure in the process of reading, writing or processing numbers

- Anxiety, agitation, or mood changes.

- Disorganized thoughts or confusion

- Lack of impulse control

As the disease advances, patients may be afflicted with severe complications including an inability to swallow or control their bodily functions. In the final stages, most patients die from fatal complications such as aspiration pneumonia.

Causes of Type 3 Diabetes

This may not be well understood with regards to type 3 diabetes, or the exact link between insulin resistance and Alzheimer's disease. Some identified contributing factors include the following:

1. Insulin Resistance

Insulin acts as an important regulatory mechanism of brain functions such as memory and cognition. The reduction in insulin signaling may impair metabolism of brain cells, thus bringing about neurodegeneration.

2. Type 2 Diabetes

These diseases show a strong relationship and those individuals diagnosed with type 2 diabetes have double chances of getting Alzheimer's. In the two, the main causes can be chronic inflammation, oxidative stress, and a defect in glucose metabolism.

3. Environmental and Lifestyle Factors

Insulin resistance associated with obesity, stress, and an unhealthy diet is considered a cause that may increase the chances of Alzheimer's disease.

Researches in Frontiers in Neuroscience and The Lancet Neurology have also highlighted that drugs used for antidiabetic medication may be crucial for the prevention or at least slowing down the course of Alzheimer's.

Treatments for Type 3 Diabetes

In 2022, in a study in Pharmaceuticals, researchers studied biomarker uptake in brain regions implicated in the faulty uptake and metabolism of blood sugar in Alzheimer’s patients.

Emerging Therapies

Research into such treatments as intranasal insulin has also been promising. Intranasal delivery of insulin directly to the brain has been reported to enhance glucose uptake by brain cells, improve memory, and boost cognitive performance. While such clinical trials have been shown to be successful, additional research is needed for safety and efficacy.

Medications

For patients being aggressive or agitated, antipsychotic drugs may be prescribed; however, therapies such as cognitive rehabilitation as well as cognitive stimulation therapy serve to preserve memory and executive function.

Lifestyle Interventions

Diet, exercise, and stress management are critical in preventing and managing insulin resistance. A review in the Journal of Alzheimer's Disease also highlighted the benefits of Kirtan Kriya meditation, which can regulate genes involved in insulin and glucose metabolism, improve sleep, and reduce inflammation.

Can Type 3 Diabetes Be Prevented?

Although type 3 diabetes is not officially recognized, its connection to Alzheimer’s disease underscores the importance of proactive measures for brain health. Some prevention strategies include:

1. Healthy Diet

Consuming a balanced diet rich in antioxidants, whole grains, and healthy fats may support brain health.

2. Regular Exercise

Physical activity improves insulin sensitivity, reduces inflammation, and enhances overall metabolic health.

3. Stress Reduction

Mindfulness practices, including meditation, have been shown to lower stress levels, which can reduce the risk of cognitive decline.

The term type 3 diabetes brings out the complex relationship between metabolic disorders and brain health. Even though it is not a recognized medical condition, the concept emphasizes the crucial role of insulin in brain function and its possible contribution to Alzheimer's disease. Continued research will hopefully provide hope for therapies such as intranasal insulin and lifestyle modifications.

Inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, affects millions of people worldwide. The lifelong condition commonly begins in adolescence or early adulthood and can require repeated hospital treatment, long-term immunosuppressive medication, and, in some cases, surgery.

Despite advances in treatment, many patients cycle through multiple therapies without achieving lasting disease control, impacting their lives and costing healthcare systems millions.

Now, a team of UK researchers from the Universities of Oxford, Newcastle, and Cambridge has identified an important driver of inflammatory bowel disease (IBD).

The findings, published in the New England Journal of Medicine, suggest that inflammatory bowel disease is not a single condition but a group of biologically distinct diseases driven by different underlying mechanisms.

"Understanding what drives the inflammation provides a clear explanation for disease in this group of people and opens the door to new treatments that target the autoantibodies themselves or cells that produce those autoantibodies," said Professor Holm Uhlig, a pediatric gastroenterologist and director of the Centre for Human Genetics, Nuffield Department of Medicine, University of Oxford.

What Did the Study Find?

The researchers analyzed more than 4,900 patients with IBD and discovered that:

• A substantial subset of patients shows autoimmune responses to one of the guardians of the immune system, interleukin-10 (IL-10), which leads to uncontrolled inflammation.
• This damaging immune response is the mechanism for one of the strongest known genetic risk factors for IBD.

Antibodies that block interleukin-10 (IL-10), a cell-to-cell messenger that normally acts as one of the body's key controls on inflammation, effectively remove the immune system's natural "brake" on inflammation, allowing inflammatory responses to continue unchecked.

The researchers found high levels of anti-IL-10 neutralizing autoantibodies in the blood of about 3.5% of IBD patients, including those with Crohn's disease and ulcerative colitis, but not in healthy individuals. This could equate to 15,000–20,000 people with IBD in the UK carrying these autoantibodies.

The Genetic Link

The researchers also found that the presence of these antibodies was strongly linked to carriage of a particular genetic variant known as HLA-DRB1*01:03.

The link between HLA-DRB1*01:03 and a severe form of inflammatory bowel disease was first identified by Oxford researchers 30 years ago.

The new findings show that people carrying this variant are far more likely to develop antibodies that block IL-10, helping explain how the gene contributes to disease.

What Could This Mean for Patients?

The researchers say the findings support the development of a blood test to identify this subgroup of patients, helping clinicians move quickly toward more appropriate treatment.

What Is IBD?

As per the Centers for Disease Control and Prevention (CDC), IBD refers to a group of lifelong diseases that affect your intestines. The main types of IBD are ulcerative colitis and Crohn's disease.

Ulcerative colitis affects the large intestine, while Crohn’s disease can inflame any part of the digestive tract. Both are lifelong conditions of unknown cause that trigger abdominal pain, diarrhea and other complications, with no known cure.

What Are The Symptoms Of IBD That People Usually Ignore?

• Diarrhea or changes in bowel movements
• Stomach pain
• Fatigue
• Nausea
• Weight loss

• Dehydration
• Increased risk of colon and rectal cancers
• Low red blood cell count (anemia)
• Reduced bone density
• Joint pain
• Skin changes
• Eye irritation
• Delayed or impaired growth in some children.

With modern lifestyle changes, delayed childbearing, and other factors, infertility among Indians as young as 25 has become a looming public health concern for the country. However, the issue does not stop at the present.

A recent study published by The Menopause Society in their journal Menopause found that infertility may lead to earlier menopause, raising questions about the long-term reproductive health implications of this demographic shift.

What is Menopause?

Menopause is the final stage of a woman’s reproductive lifecycle, when menstruation stops, and she can no longer get pregnant. When the ovaries stop producing estrogen and progesterone, and a woman misses her period for 12 consecutive months, she has officially reached menopause.

Although menopause is a regular part of ageing, women typically reach menopause between 45 and 55 years of age. If menopause occurs before age 45, it is considered early menopause. If it occurs before 40, it is termed premature menopause – rarer than early menopause but involves the same causes, symptoms, and health risks.

While previous studies have been conducted to find a link between infertility and both early and premature menopause, they have had mixed results and did not consider the effect of different types of infertility; this study focuses on women with a history of primary infertility, women who have never achieved pregnancy, and have difficulty conceiving.

What Did the Study Find?

For the study, researchers examined the reproductive lifecycle of nearly 700 women in the U.S. – 461 with primary infertility and 530 without infertility – who were otherwise demographically similar (age, education, smoking status, etc.). It found that the 461 women had a 25% higher likelihood of reaching natural menopause about 1.2 years earlier than the 530.

Researchers also noted that women with underlying endometriosis as a cause of their infertility reached menopause between 40 and 44 years, much sooner than the national average of the United States, i.e., 52 years.

Possible explanations include accelerated ovarian ageing, reduced ovarian reserve, or the effects of endometriosis on ovarian function. But no matter the causes, the implications for women’s long-term health are substantial.

Why Does This Matter?

All women are born with a finite, predetermined number of eggs, which are sensitive to age, environmental toxins, medications, hormonal imbalances, and lifestyle factors. When exposed to such risk factors, especially over a long period of time, the DNA inside the eggs is altered, causing permanent genetic damage and reducing the egg quality and quantity.

As a core part of the reproductive process, any damage to the eggs directly affects reproductive health and, in turn, long-term systemic health.

Infertility impacts more than the ability to conceive and go through a pregnancy; it is often a sign of underlying health conditions and potential chronic illnesses, acting as a biomarker of increased all-cause mortality. Experiencing infertility itself increases a woman’s risk of developing cardiovascular disease, metabolic disorders, gynecologic cancers, etc., but reaching menopause early on top of that puts them at further health risk, adding osteoporosis and cognitive decline to the mix, along with the emotional distress and mental health challenges.

Indian women already reach menopause earlier than women in Western countries, with the average woman experiencing menopause at 46.2 years of age. With fertility rates dropping across the country, this study highlights just how critical it is to increase fertility awareness. Early screenings and regular fertility testing can help detect risks early and enable timely intervention, not only to combat the ongoing crisis but to ensure that women live healthy, fulfilling lives without impending morbidity.

A new oral GLP-1 medication has delivered encouraging results in a Phase 2b clinical trial for people living with type 2 diabetes.

According to AstraZeneca, its experimental tablet, elecoglipron, significantly lowered blood sugar levels and helped participants lose an average of 10.5% of their body weight after 26 weeks of treatment.

The findings were presented at the 2026 American Diabetes Association Scientific Sessions in New Orleans and published in The Lancet on June 8.

Elecoglipron joins a growing wave of GLP-1 therapies being developed as pills, offering an alternative to injectable drugs such as Ozempic, Wegovy, Zepbound, and Mounjaro.

The first oral GLP-1 treatment, Rybelsus from Novo Nordisk, received FDA approval in 2019 for adults with type 2 diabetes. Since then, oral options have continued to expand. In December 2025, the FDA approved a tablet version of Wegovy for weight management, while Eli Lilly’s oral obesity treatment, Foundayo, gained approval in April.

Independent experts say AstraZeneca’s results highlight the growing potential of non-injectable GLP-1 therapies for both diabetes and obesity treatment.

“It’s encouraging to see another oral medication demonstrating the benefits of GLP-1 therapy without requiring injections,” said Dr. Pouya Shafipour, a family and obesity medicine specialist at Providence Saint John’s Health Center in California.

Dr. Marilyn Tan, an endocrinologist and professor of medicine at Stanford University, noted that the rapidly expanding GLP-1 market could soon welcome another oral treatment option if elecoglipron succeeds in Phase 3 trials and ultimately secures FDA approval.

How Does GLP-1 Drug Work?

GLP-1 is 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 they 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. GLP-1 pills imitate that hormone, thereby silencing the food chatter in the brain. Interestingly, for some people, this food chatter is really quiet, and for others it is an outburst. So with GLP-1, 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 them at 12 weeks; therefore, it is important for some but not for others.

What Are The Side Effects?

The side effects of these pills include:

• Nausea is a frequent side effect, especially when starting or increasing the dose, and vomiting may occur along with nausea.
• Diarrhoea and abdominal discomfort also show up.
• It 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, 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.
