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.

When Demi Moore stepped onto the red carpet at the 2026 Actor Awards, the conversation quickly shifted away from couture and glamour. The 63 year old actor wore a striking black Schiaparelli gown with a dramatic feathered train, but what truly caught public attention was her noticeably thinner frame.
Photos from the event spread rapidly across social media, and many fans expressed worry over what they described as a “skeletal” appearance. Some questioned whether the transformation was intentional. Others speculated whether she may have used Ozempic, the diabetes medication that has become synonymous with rapid celebrity weight loss.
There has been no confirmation that Moore used any weight loss medication. Still, the public reaction reflects a growing anxiety about how quickly bodies can change in the era of injectable weight loss drugs.
Ozempic was originally developed to help manage type 2 diabetes. Its active ingredient, semaglutide, works by mimicking a hormone that regulates blood sugar and appetite. Over the past few years, it has gained immense popularity for its ability to produce significant weight loss.
But as prescriptions surged, so did questions about side effects. One of the biggest concerns is loss of lean mass, which includes muscle.
Research published in Cell Metabolism examined how semaglutide affects body composition. In animal studies, overall lean mass dropped by about 10 percent during weight loss. Interestingly, much of that loss was not from skeletal muscle but from organs like the liver, which can shrink as body fat decreases. Some skeletal muscles did shrink slightly, by about 6 percent on average, while others remained unchanged.
However, other human studies suggest that people taking semaglutide may lose a substantial amount of muscle along with fat. One study found that around 39 percent of the weight lost was muscle. Research on tirzepatide, another injectable drug, showed muscle loss closer to 25 percent of total weight reduction.
It is important to note that muscle loss is not unique to Ozempic. Anytime someone loses a large amount of weight, whether through dieting, surgery, or medication, about one quarter to one third of that loss can come from muscle. When calories are restricted, the body taps into stored energy from glycogen, fat, and muscle.
The problem is that muscle matters. Losing muscle lowers metabolic rate, increases fatigue, and can raise the risk of falls or injury, especially in older adults. For women over 60, rapid weight loss may also affect bone health.
When a public figure appears dramatically thinner within a short span of time, people naturally worry. Rapid weight loss can sometimes signal aggressive calorie restriction, illness, or medication side effects.
Even when weight loss is intentional, the speed matters. Quick changes can strain the body, impact strength, and alter facial structure, which may explain why some fans said Moore looked “different” rather than simply “slimmer.”
Healthy weight loss is not just about a number on the scale. It is about preserving muscle, supporting metabolism, and protecting long term health.
If someone chooses to pursue weight loss, whether naturally or with medical supervision, protecting muscle should be a priority.
Prioritize protein. Most adults aiming for fat loss need between 60 to 90 grams of high quality protein daily. Protein supports muscle repair and helps maintain lean mass, especially when appetite is reduced.
Strength train consistently. Resistance training at least three to four times a week signals the body to hold onto muscle. Lifting weights, using resistance bands, Pilates, or bodyweight exercises all help.
Do weight bearing cardio. Walking, tennis, or light jogging can support both bone density and muscle retention.
Stay hydrated. Muscle is largely made of water. Dehydration can worsen fatigue and impair recovery.
Aim for slow, steady loss. Losing weight gradually gives the body time to adapt and reduces the risk of excessive muscle breakdown.
Demi Moore’s appearance has reignited a broader conversation about beauty standards, aging, and the pressures surrounding thinness. Regardless of the cause behind her transformation, the moment highlights an important truth. Sustainable health is about strength, balance, and care, not just shrinking numbers on a scale.
Multivitamins are essentially dietary supplements containing a combination of various vitamins and minerals, often used to bridge nutritional gaps in the diet, treat deficiencies caused by poor nutrition or illness and support overall health.
Designed to provide a broad range of nutrients in one daily dose, they are available in tablets, capsules, gummies or liquids and are widely recommended to adults of all ages and genders.
But which vitamins do women need and when should you be taking them?
Dr Yashica Gudesar, Director & Unit Head of Obstetrics & Gynecology, Max Super Speciality Hospital, Dwarka exclusively tells Healthandme: "A woman’s nutritional needs change at different stages of life, from adolescence to reproductive years, pregnancy, and menopause. While food should always be the primary source of nutrients, certain vitamins may be required as women age or depending on lifestyle, diet, and health conditions."
"There’s honestly no universal vitamin checklist that works for every woman. The needs change with age, lifestyle, stress, whether one is planning a pregnancy, and of course, what the blood reports actually show," Bhakti Samant, Chief Dietician, Kokilaben Dhirubhai Ambani Hospital further told this publication.
Here are the supplements you need to stock your medicine cabinet with:
Vitamin D is a fat-soluble nutrient essential for strong bones, immune function, and calcium absorption, often synthesized when skin is exposed to sunlight or obtained via food and supplements.
Symptoms of Vitamin D deficiency include bone pain, muscle weakness, and depression. Deficiencies are common due to low sun exposure or poor diet, leading to rickets in children and osteomalacia or osteoporosis in adults.
However, this can be avoided by consuming a combination of calcium and Vitamin D supplements. Dr Ginni Kalra, Head Dietician, Aakash Healthcare explained to Healthandme: "One of the frequently deficient nutrients in women is vitamin D. It is very important in calcium absorption, bone density, immune homeostasis and mood balance. In most adult women, the amount needed is 600-800 IU (15-20 mcg) per day although deficient women can take 1000-2000 IU per day under the supervision.
"Calcium is necessary in bone density especially in women post-menopause who experience rapid bone loss owing to the diminishing estrogen. Adult women should take 1,000 mg per day that rises to 1200 mg past 50 years. Calcium supplements are most ideal in separated doses of 500-600 mg each time and preferably following meals. When combined with vitamin D, absorption will enhance much better."
"Calcium becomes especially important after the age of 30, and even more after menopause. It can be taken after meals, often divided into two doses for better absorption," Dr Gudesar added.
Moreover, Samant advised: "Vitamin D is best taken with a meal that has some fat. Calcium (around 1000–1200 mg daily) is better split into two doses and should not be taken with iron."
A vital mineral, iron plays a very crucial role in human functioning by helping create hemoglobin to transport oxygen throughout the body, essential for energy and muscle function. Low iron levels can result in decreased oxygen transport and leading to symptoms like extreme fatigue, weakness, pale skin, cold hands/feet and shortness of breath.
While an iron deficiency is usually caused by poor diet, blood loss due to menstrual periods, ulcers, cancer, or regular use of pain relievers like aspirin or malabsorption issues, it can be remedied through supplements.
Dr Kalra explains: "Iron is also essential especially in menstruating women because they lose blood monthly. It may result in an iron deficiency which causes fatigue, loss of hair, brittle nails, and poor concentration. The acceptable amount of iron that is recommended to be taken by women aged 19 to 50 is approximately 18 mg, but this reduces to 8 mg after menopause.
"Iron supplements are better absorbed on an empty stomach or when taken with vitamin C and not when they are taken with calcium, tea or coffee as they have been found to interfere with absorption. The intake in the morning is usually desirable, but in case of gastrointestinal discomfort, it should be avoided."
Vitamin C is essential for the body because it serves as a powerful antioxidant, supports the immune system, and is crucial for the synthesis of collagen, which is vital for wound healing and the maintenance of healthy skin, bones, and blood vessels.
It also enhances the absorption of iron from plant-based foods and protects cells from damage caused by free radicals, potentially reducing the risk of chronic diseases like cancer and heart conditions.
While, foods such as oranges, lemons, red and green peppers, kiwifruit, broccoli, strawberries, and Brussels sprouts can provide help maintain Vitamin C levels, supplements can help boost absorption and maximize benefits.
Dr Kalra notes: "Vitamin C helps to maintain the immunity, collagen synthesis, and iron uptake. It should be taken in 75 mg daily by adult women. It is soluble in water and can be consumed together with breakfast."
Additionally, she also recommends intaking: "Vitamin E and vitamin A also help the skin, vision, and antioxidant defense, but overconsumption is not advisable because it may be toxic."
Omega-3 fatty acids are polyunsaturated fats known for their crucial role in brain function and overall mental health. Fish oil is particularly rich in EPA and DHA, which are vital components of cell membranes and have strong anti-inflammatory effects in the body.
These omega-3s play a critical role in human development, and they are primarily found in fatty fish and fish oil. Some popular sources of Omega-3 include:
But as many people do not consume enough fish, supplementation is often recommended to ensure adequate intake of these essential fatty acids.
Dr Kalra suggests: "Though not vitamins, omega-3 fatty acids are worth mentioning because of the cardiovascular, hormonal, and anti-inflammatory effects. About 250–500 mg of combined EPA and DHA a day may be helpful and is most often administered after meals."
Symptoms of a Vitamin B12 deficiency often appear slowly. You may not notice them at first, or may blame them on stress, lack of sleep or a busy schedule. However, if the deficiency continues for long, it could lead to serious health problems.
Dr Gudesar recommends: "Vitamin B12 supports nerve health and energy levels. Vegetarian women are more prone to deficiency. It is typically taken in the morning."
"Vitamin B12 is needed to promote nerve well-being, red blood cell building, and energy conversion. The chances of deficiency are increased in vegetarian women because B12 is mostly found in foods of animal origin. The suggested daily dose is 2.4 mcg, but the dosage can be raised in deficiency. It is preferable in the morning as it could increase alertness," Dr Kalra explained.
However, Dr Kalra also advises: "There should be individualization of supplement timing and dosage. Decisions should be based on routine blood tests, dietary assessment, age, lifestyle, and existing medical conditions.
"Excessive supplementation is detrimental, in particular, fat-soluble vitamins. The only safe and effective approach is nutritional adequacy by means of whole foods, and supplements are the supportive therapy only in cases where deficiencies are observed."

The digital revolution has transformed childhood. From online classes to gaming and entertainment, headphones and earphones have become constant companions for children. While technology has brought convenience and learning opportunities, it has also introduced a silent threat, damage to children’s hearing.
In my clinical practice as an ENT surgeon, I am witnessing an alarming increase in young patients presenting with symptoms such as ear discomfort, ringing in the ears (tinnitus), and reduced hearing ability. These issues, once uncommon in children, are now becoming increasingly frequent due to excessive and unsafe use of personal audio devices.
What makes the situation more concerning is that children often do not recognize the early warning signs. By the time symptoms become noticeable, significant damage may have already occurred.
• Listen at no more than 60% of the maximum volume
• Limit usage to 60 minutes at a time, followed by a break
This simple guideline can significantly reduce the risk of hearing damage and should be strictly followed by children and adolescents.
• Frequently increasing the volume of devices
• Complaints of ringing, buzzing, or ear pain
• Difficulty in hearing conversations
• Speaking unusually loudly
If any of these symptoms are noticed, it is important to consult an ENT specialist promptly.
1. Limit Earphone Use: Encourage children to use speakers whenever possible instead of earphones.
2. Choose Safer Devices: Over-the-ear headphones are generally safer than in-ear earbuds as they reduce direct sound impact.
3. Ensure Quiet Environments: Avoid using headphones in noisy surroundings, as children tend to increase volume to compensate.
4. Take Regular Breaks: Continuous listening should be avoided. Short breaks help the ears recover.
5. Avoid Night-time Use: Using headphones before sleep can harm both hearing and sleep quality.
Routine hearing check-ups should also be encouraged, especially for children who frequently use headphones for study or entertainment.
The digital age is here to stay, and technology will continue to play a central role in children’s lives. However, safeguarding their health must remain a priority. Hearing is a precious sense that, once lost, cannot be restored.
By adopting simple precautions, spreading awareness, and encouraging responsible use of technology, we can ensure that our children enjoy the benefits of the digital world, without compromising their hearing health.
