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.
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.
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.
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:
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.
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.
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.
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.
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.
If stress is making you turn to alcohol, over time it may lead to fatty liver. (Photo credit: iStock)
Many people do not realise just how closely mental health and liver health are connected—especially when alcohol becomes a go-to coping strategy for stress, anxiety, or emotional overwhelm. What may seem like temporary relief can quietly evolve into a pattern that affects both the mind and the body in significant ways. Dhara Ghuntla, Psychologist affiliated with Sujay Hospital, 7 Hills Hospital, Criticare Hospital, in an interaction with Health and Me, spoke about the impact of stress, alcohol use and emotional eating on the liver.
In today’s fast-paced, high-pressure lifestyle, it is common for individuals to turn to alcohol to unwind or escape difficult emotions. In the short term, alcohol can create a sense of relaxation or numbness. However, over time, this reliance can shift into a habitual coping mechanism and eventually into dependence. While the psychological impact is often discussed, the physical consequences—particularly on the liver—are just as important.
The liver plays a critical role in detoxifying the body. Regular alcohol consumption places it under constant strain, impairing its ability to function effectively. Over time, this can lead to conditions such as fatty liver, inflammation, and even long-term liver damage. What makes this especially concerning is that early-stage liver issues often present with little to no obvious symptoms, allowing damage to progress unnoticed.
At the same time, liver health has a direct influence on mental well-being. When the liver is compromised, it can affect energy levels, mood regulation, and cognitive function. People may experience increased fatigue, irritability, anxiety, low mood, or emotional instability. This happens because the liver plays an indirect but essential role in brain health through metabolism and toxin clearance.
The Vicious Cycle
This creates a self-perpetuating loop. A person feeling stressed, low, or anxious may turn to alcohol for relief. While it may help temporarily, it simultaneously places stress on the liver. As liver function declines, mental health symptoms—such as fatigue, irritability, anxiety, or low mood—can worsen. This often leads the individual to consume more alcohol, reinforcing the cycle.
Adding another layer, many individuals who rely on alcohol are often dealing with underlying issues such as depression, anxiety, sleep disturbances, or chronic life stressors. Alcohol is frequently used as a form of self-medication. However, instead of addressing these root concerns, it masks them temporarily while deepening both psychological and physical harm. Over time, this pattern increases dependency and makes recovery more complex.
Liver health is also closely tied to gut function and brain health. When the liver is under stress, digestion can be affected, nutrient absorption may decline, and energy levels can drop. This interconnected system—the gut, liver, and brain—plays a key role in emotional regulation and overall well-being. Disruptions in one area can ripple across the others, influencing how a person thinks, feels, and functions daily.
Breaking the Pattern
Recognising this connection is the first step towards change. Instead of turning to alcohol, healthier coping strategies can help regulate stress and support both mental and physical health. Practices such as yoga, meditation, regular exercise, journalling, and maintaining a balanced diet can significantly improve resilience and emotional stability.
Prioritising mental well-being, addressing underlying psychological concerns, and protecting liver health are not separate goals—they are deeply interconnected. Seeking timely support, whether through therapy, lifestyle changes, or medical guidance, can help break the cycle.
Reducing or eliminating alcohol use is not just about avoiding physical harm; it is about creating space to heal the underlying causes of stress and emotional distress. Supporting the liver, nurturing the gut, and caring for mental health together can lead to more sustainable and meaningful well-being.
Bursitis is often linked to lifestyle. (Photo credit: iStock)
You pick up a jar on the kitchen shelf and shudder. You take a flight of stairs, and that old pain sinks into your hip. You get up in the morning, and your shoulder feels as though it has been wrung out. You attribute it to age, to a long day on your feet, to just how things are now. But what if your body is trying to tell you something very particular and you have been missing it?
Dr Apoorv Dua, Consultant, Orthopaedics, ISIC Multispeciality Hospital, in an interview with Health and Me, said that this may be a sign of bursitis—a condition that is much more widespread than most people realise, and much more treatable than most people are aware. The expert went on to answer common questions regarding extreme pain that comes with this condition.
Bursae are small, fluid-filled sacs located between your bones, muscles, and tendons. Imagine them as the natural cushioning system of the body—shock absorbers that ensure your joints move smoothly and painlessly. Under normal circumstances, you do not even think about them. However, when inflamed, due to repetitive motion, prolonged pressure, injury, or infection, they make their presence known in a very noticeable manner. This is bursitis. Although it most often appears in the shoulder, elbow, hip, and knee, it may occur in nearly any joint in the body.

This is where the lifestyle connection cannot be overlooked. Bursitis does not discriminate, but it has definite patterns. The weekend warrior who runs ten kilometres on Saturday after sitting at a desk all week. The housewife who spends hours cleaning floors or squatting in the kitchen. The office worker who has been stooped over a computer. The gym enthusiast who does not warm up. The retired teacher who begins a walking routine too vigorously. All these individuals may be silently placing stress on their bursae, and in many cases, bursitis is the eventual outcome.
Age also plays a role—the bursae, like most of our connective tissue, grow weaker with age. Certain medical conditions such as rheumatoid arthritis, gout, and diabetes can increase the risk. However, in many instances, the cause is simply the way we move—or do not move—in our day-to-day lives.
A key characteristic of bursitis is pain that is disproportionate to the activity causing it. Reaching overhead, sitting on a hard surface, pressing on your elbow, or walking downhill—these are not dramatic movements, yet with bursitis, they may trigger a sharp, deep, or burning pain that interrupts you mid-action. The affected joint is usually swollen and tender. The area may feel warm to the touch. Movement becomes guarded. Sleep, particularly in cases of shoulder bursitis, can be difficult, as lying on the affected side aggravates the pain.
The challenge with bursitis is that its symptoms can resemble other conditions—tendinitis, arthritis, a muscle strain, or even a ligament tear. Many individuals self-diagnose, self-treat with painkillers, and hope it will go away. Sometimes it does. However, chronic, untreated bursitis may persist for months and, in some cases, lead to complications.

A thorough clinical examination is usually the first step. A skilled orthopaedic specialist can identify the affected bursa through specific physical assessments. Imaging, such as ultrasound or MRI, may be recommended depending on the case to confirm the diagnosis, rule out structural damage, or guide treatment.
If infection is suspected—indicated by increased redness, fever, and rapidly worsening pain—fluid may be aspirated from the bursa and tested. Septic bursitis is a serious condition that requires immediate medical attention and is treated differently from the more common non-infectious type.
The encouraging fact about bursitis is that it responds well to treatment, particularly when detected early. Most cases are managed with a combination of rest, activity modification, ice application, and anti-inflammatory medication. Physiotherapy also plays an important role, helping to correct movement patterns, strengthen supporting muscles, and restore the full range of motion.
In more persistent cases, a corticosteroid injection into the bursa may provide rapid and significant relief by reducing inflammation at its source. Surgery is rare and is typically considered only in chronic, recurrent cases that do not respond to conservative treatment.
In many instances, bursitis is linked to lifestyle—and that presents an opportunity for prevention. Even small changes can help: warming up before exercise, avoiding excessive strain on joints, maintaining a healthy weight to reduce pressure on hips and knees, and ensuring workstations are ergonomically designed.
Pain often becomes background noise—something we get used to, work around, and push through. However, bursitis reminds us that the body communicates with precision. That pain when you pick up a jar, that discomfort on the stairs—it is not simply ageing. It is a signal worth discussing with your doctor.
Robotic hernia surgery is less invasive. (Photo credit: iStock)
The bulge that appears when an internal organ pushes through a weakened muscle wall will not recede with rest or medication—it will, in most cases, grow larger and more uncomfortable over time. Surgery is the only definitive treatment. What has changed significantly in recent years is what that surgery looks like and what recovery from it requires.
Dr Rajesh Sharma, Director – General Surgery, Minimal Access & Bariatric Surgery, CK Birla Hospitals, Jaipur, in an interview with Health and Me, spoke about the introduction of robotics in hernia treatment and how it can benefit patients.
With advances in surgical technology, minimally invasive approaches have significantly improved patient outcomes. One of the most important developments in recent years is robotic-assisted hernia surgery using the da Vinci Surgical System. In robotic surgery, the surgeon operates from a console equipped with a high-definition, three-dimensional, magnified view of the surgical field. The robotic system translates the surgeon’s hand movements into extremely precise movements of miniaturised instruments inserted through small incisions. The system also filters natural hand tremors and provides a greater range of motion than the human wrist, enabling meticulous dissection and suturing.
For hernia repair, these capabilities allow surgeons to perform delicate steps such as accurate defect closure and optimal mesh placement, which are important for the long-term durability of the repair.
Robotic hernia repair offers several advantages for patients:
Because the procedure is minimally invasive, most patients experience earlier mobilisation and quicker overall recovery compared with traditional open surgery. Robotic surgery is particularly useful in complex, recurrent, or large ventral hernias, where precise reconstruction of the abdominal wall is important. While not every hernia requires a robotic approach, the technology expands the surgeon’s ability to perform advanced minimally invasive repairs with improved ergonomics and visualisation.
The future of hernia surgery
The integration of robotic platforms such as the da Vinci system represents a major step forward in modern general surgery. By combining surgical precision with minimally invasive techniques, robotic hernia repair aims to enhance patient comfort, improve recovery, and deliver durable surgical outcomes.
