What Is Type 3 Diabetes? Insulin Resistance In The Brain That Could Trigger Alzheimer’s

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.

From Stress to Steatosis: How Modern Lifestyles Are Impacting Liver Health

Updated Apr 28, 2026 | 07:00 AM IST

SummaryAs cells become less responsive, insulin levels rise, and the excess glucose is eventually stored as fat. This fat doesn’t just remain visible; it can quietly accumulate in the liver and begin to interfere with how it works.

The liver is one of the body’s most dependable organs, quietly doing its job in the background every single day. It handles over 500 essential functions—from filtering out toxins and producing key proteins to helping with digestion through bile and keeping your metabolism running smoothly. Most of the time, it does all of this without demanding attention.

For years, liver disease has largely been associated with alcohol. But today, a quieter and increasingly common condition is coming into focus: Non-Alcoholic Fatty Liver Disease (NAFLD), or steatosis. Closely linked to the way we live today, it is affecting a growing number of people, often without any clear warning signs. At the heart of this shift are three closely linked factors: ongoing stress, everyday eating habits that have slowly gone off track, and a noticeable drop in physical activity.

Stress, though often brushed aside, has a real and lasting impact on metabolic health. When the body is constantly in a “fight or flight” mode, cortisol levels stay high. Over time, this often shows up as fat, especially around the abdomen, while also affecting how the body handles insulin. As cells become less responsive, insulin levels rise, and the excess glucose is eventually stored as fat. This fat doesn’t just remain visible; it can quietly accumulate in the liver and begin to interfere with how it works. At the same time, persistent low-grade inflammation creates a setting where the condition can slowly worsen over time.

Diet plays an important role as well. Regularly eating processed foods, refined carbs, and added sugars can quietly tip the body into a calorie surplus, slowly straining its metabolic balance. Fructose—commonly found in sweetened drinks and packaged foods—is largely processed by the liver, putting even more pressure on it over time. When consumed in excess, it pushes the body to convert more sugar into fat, which then starts building up within liver cells over time.

A sedentary lifestyle only adds to this, often without us even realizing it. Because there is little mobility, the body becomes inefficient in using fats and carbohydrates. Over time, weight gain occurs, the body develops insulin resistance, and fatty deposits begin to form in the liver.

Sleep, which is usually ignored, is crucial. If there is insufficient or poor-quality sleep, the body’s circadian rhythm will be disrupted, as well as hormones like ghrelin and leptin, which regulate feelings of hunger and fullness. This increases food consumption and reduces energy expenditure, enabling fat deposition.

The hardest thing about NAFLD is that it is a silent disease. In the first stages of NAFLD, there will be no symptoms felt by the patient. This condition is often diagnosed incidentally when patients undergo physical checkups. Thus, untreated steatosis would eventually turn into NASH, wherein inflammation and injury of liver cells occur. The process then proceeds to fibrosis, cirrhosis, and in severe cases, transplantation of the liver.

The reassuring part is that NAFLD can often be reversed when caught early. In many cases, it comes down to simple, steady choices, eating balanced meals with whole grains, fruits, vegetables, and lean proteins, and staying physically active. Small habits like managing stress through mindfulness or yoga, and getting enough sleep, can make a real difference to metabolic health.

For those at higher risk, including people with obesity, diabetes, or high cholesterol, regular health check-ups become especially important. Spotting the condition early gives you a chance to act before it moves into more serious stages.

The liver, after all, keeps working quietly in the background every single day. Looking after it doesn’t require anything extreme, just consistent, everyday choices that add up over time.

The ‘Always Stressed’ Generation: How Cortisol Is Quietly Impacting Female Fertility

Updated Apr 27, 2026 | 09:30 PM IST

SummaryCortisol is the stress hormone, which does have a positive impact in certain situations. However, high levels for a prolonged period can hurt reproductive health in women.

Right now, days' stress no longer comes in bouts; bouts have been turned to a continual rhythm. Deadlines, working overtime, staring at computer screens, lack of sleep, and daily tensions, together with environmental pollution, have resulted in what physicians have started to call the "always stressed" generation. Things like cortisol, the body's primary stress hormone, which is linked to changes in female fertility, albeit subtly, are being blamed more and more nowadays.

Is cortisol making women infertile?

In an interview with Health and Me, Dr. Rubina Pandit, Fertility Specialist, Nova IVF Fertility, Basaveshwaranagar, spoke about the impact of cortisol on fertility in women.

Cortisol is a great help when the body is responding to stress. Among other functions, it regulates energy, metabolism, and immunity. The trouble begins with stress that is sustained for a long time and cortisol levels that remain high continuously. Then it starts to cause disruptions to reproductive health.

The latest studies conducted in 2025 and 2026 indicate that stress over a long period may affect the hormonal balance required for ovulation. A high level of cortisol also changes the brain signals that are responsible for the regulation of the ovaries and that can cause irregular periods or even absence of ovulation. In other words, chances for natural conception will be diminished if ovulation doesn't occur regularly.

More intriguingly, recent research has discovered some new findings about the impacts of stress on infertility. According to a 2026 study, cortisol hormone levels could modify the uterine environment and influence the genes that facilitate embryo attachment and development. In this case, the effect of stress could not only affect ovulation but also interfere with the successful growth of fertilised embryos.

Infertility and chronic stress: The link explained

Another area of study that researchers have focused on is the possible connection between infertility and chronic stress. Recent scientific studies suggest that women under constant stress have markers that signal reduced ovarian functioning. Moreover, prolonged stress is known to negatively affect sleep, libido, and even romantic relationships of couples.

That said, it is worth mentioning that stress is unlikely to be the only reason for infertility issues. However, stress usually exacerbates all other reproductive problems and makes them very hard to manage. The emotional load is, in fact, one of the least acknowledged side effects of stress. A lot of women who are treated for fertility issues complain about being stressed. And due to this stress, some of them even give up on their treatment. This is a direct indication that mental health and fertility work in tandem.

The main point is that fertility is more than just hormones or medical intervention; it is the overall well-being that matters. Changing stress levels by having good sleep, exercising regularly, practicing mindfulness, or even getting professional help can have a great impact. In a generation that is always switched on, learning how to slow down might be one of the most important steps toward improving fertility.

Spending hours at work is one thing, but spending countless hours at the same desk just to meet deadlines is a habit that not only takes a toll on mental health but also on physical well-being. That being said, the rising incidence of spine problems is concerning—once a problem of the elderly, it is now affecting younger people as well. However, due to the age factor, several people tend to ignore spine problems, but they continue to worsen silently. In such a scenario, early and regular health checks can help prevent pain, stiffness, and long-term disability.

Dr Harshal Bamb, Senior Consultant and Spine Surgeon at Gleneagles Hospital, Parel, listed some of the key tests for the spine that can help with the early diagnosis of health problems. It is time to focus on spine health and improve quality of life.

Why have spine problems become common?

Currently, many people are struggling with spine problems. With long working hours, poor posture, excessive screen time, and a lack of physical activity, spine-related problems can steal peace of mind. Spine problems are conditions that affect the bones, discs, nerves, or muscles of the back and neck. These may include issues such as muscle strain, slipped or herniated discs, cervical or lumbar spondylosis, and spinal deformities such as scoliosis that can interfere with daily activities.

What are the symptoms of spine problems?

It is essential to seek help for signs and symptoms such as back or neck pain, stiffness, tingling or numbness in the arms or legs, reduced flexibility, and difficulty in standing or sitting for long periods. In more severe cases, it can also lead to weakness or nerve compression in patients. Timely awareness and routine checks can help prevent complications such as immobility, pain, nerve damage, and posture problems. If left untreated, spine problems can impact quality of life.

Health tests that can help diagnose spine problems

Dr Bamb, in an interview with Health and Me, spoke about the key spine health checks that can be helpful for people dealing with severe pain and strain.

  1. Posture check: The expert will examine regular sitting and standing posture, especially during work hours. So, if you have back pain due to poor posture, then seek immediate help. Posture evaluation is important for everyone.
  2. Pain monitoring: The expert will track any recurring back or neck pain instead of ignoring it.
  3. Flexibility test: Check your ability to bend, twist, and move without discomfort. Do the range of motion (ROM) test as suggested by the doctor.
  4. Nerve symptoms check: Watch for tingling, numbness, or weakness in the limbs. A neurological examination (sensory and motor assessment) will be conducted.

Evaluating lifestyle habits such as long sitting hours, obesity, and lack of exercise is also key to understanding spine health. Spine risk assessment or even musculoskeletal risk screening is also important. So, take these tests and keep your spine healthy.

Just like regular health check-ups for the heart, joint and spine check-ups are also important. Maintaining good posture, staying active, stretching, exercising daily, and seeking timely medical advice can help to protect the spine. Do not engage in strenuous activities mindlessly and pay attention to your spine.
