Do people consider T2DM an autoimmune condition?
No, type 2 diabetes mellitus (T2DM) is not an autoimmune disease.
The term autoimmune disease describes when the immune system attacks and damages healthy cells in the body by mistake. Although some research suggests that the immune system may play a role in the development of T2DM, most health experts classify it as a chronic metabolic disorder . This describes conditions that affect any aspect of metabolism.
Conversely, unlike T2DM, type 1 diabetes mellitus (T1DM) is an autoimmune disease. Health experts consider T1DM an autoimmune condition because it occurs when the body's immune system mistakenly attacks and destroys the beta cells in the pancreas, which are responsible for producing insulin.
T2DM happens when the body cannot use insulin effectively and the cells in the body eventually develop insulin resistance, or impaired insulin sensitivity.
This causes insulin to be less effective. As a result, more insulin is necessary to enable cells to use glucose in the blood. Over time, this can cause the beta cells in the pancreas to wear out. Eventually, the pancreas is no longer able to produce enough insulin to overcome the cells' resistance. This leads to higher blood glucose levels, and ultimately T2DM.
While researchers do not fully understand what causes problems with insulin production and resistance, risk factors for T2DM can include : having obesity
being 35 or older
a family history of T2DM or personal history of gestational diabetes
not being physically active
smoking
having prediabetes
being African American, American Indian, Asian American, Hispanic, Latino, or Pacific Islander

EXCLUSIVE Hidden link between cancer and guilty pleasures every American secretly indulges in
A sip of wine. A craving for pizza. A full calendar. These may seem like harmless aspects of life - but a scientist has revealed how they could be putting you on the brink of developing cancer. Dr Raphael Cuomo, a University of California, San Diego medical professor, claims chronic stress, fast food and alcohol and drugs are a near-surefire way to set yourself up for a cancer diagnosis later in life. In his new book, Crave: The Hidden Biology of Addiction and Cancer, the expert noted that the body's repetitive desire to indulge in junk food and addictive behaviors drives the body to the deadly condition. The professor told 'Crave reveals how modern habits like vaping, binge-eating, and daily cannabis use hijack our biology. 'These behaviors quietly damage the body's ability to repair itself. Over time, they open the door to cancer. It is not about genetics or bad luck. It is about the choices we make every day.' Over 600,000 Americans and more than 150,000 Brits die of various cancers every year. As of 2025, The American Cancer Society estimates there are over 2million new cancer cases diagnosed annually. After studying 'millions of patient records' from across the University of California hospitals and spending months reviewing studies on cancer biology, Dr Cuomo revealed what he says are the top habits most likely to cause cancer. Fast food The expert called eating fast food 'slow poison' - noting that its effects cannot be seen immediately but can cause long-term damage. Earlier this year, researchers tested more than 300 foods sold at restaurant chains and in grocery stores across America for two microscopic toxins that have been linked to cancer, infertility and autism. They found that of all fast food restaurants, the salad chain Sweetgreen and Starbucks scored poorest. Sweetgreen's Chicken Pesto Parm Salad and Starbucks' matcha latte was found to contain the highest amount of phthalates, a group of chemicals used to make plastics more flexible and transparent. Phthalates are commonly used in food packaging materials and studies have shown they imitate the body's hormones and interfere with the production of - and response to - natural hormones like estrogen and testosterone. Some phthalates have been linked to certain cancers, particularly breast cancer and lymphoma. However, Dr Cuomo pointed towards fiber consumption as a critical part of reversing damage as it can help improve gut bacteria, reduce inflammation and keep cells healthy. Smoking and drinking Smoking causes about 30 percent of overall cancer deaths in the US and is a leading cause of lung, brain, neck and bladder cancer. Alcohol consumption has been linked to an increased risk of several types of cancer, including breast, colon, liver and esophageal cancer. About 20,000 people die of alcohol-related cancers annually. Researchers in Germany found that a combination of drinking and smoking significantly raises the risk of colon cancer in young Americans. They analyzed two dozen studies comparing regular drinkers and smokers to people who abstained from both. Just 100 cigarettes in a person's lifetime - the equivalent of one per week for two years - was linked to a 59 percent higher risk of colon cancer compared to people who have never smoked. They also found drinking alcohol every day raised the risk of developing early-onset colon cancer by 39 percent, even if it's just one or two drinks per day. Alcohol and smoking have both been linked to cancer in the past, as they release chemicals that destroy DNA and cause cells to mutate. And each can of beer or glass of wine per day further increased the chance by an additional two percent. In his book, the professor noted that deep sleep is the 'most underestimated tool' to improve damage caused by addictions, such as smoking and drinking. He explained that during consistent deep sleep, the body performs critical tasks such as repairing tissues, regulating hormones, consolidating memory and clearing metabolic waste. Stress A 2024 study presented at the United European Gastroenterology Week by a group of Chinese researchers noted that a combination of chronic stress and anxiety has been linked to colorectal cancer in young people. They explained when a body is under frequent stress, a number of healthy bacteria that live in the gut start dying off, making it easier for cancer to move in. When these bacteria die off, tumors grow more quickly, leading to more aggressive, rapidly growing colorectal cancers. Research from Trinity College in Ireland has suggested these bacteria support the body's immune system, can protect against virus and bacteria and prevent damage in gut cells. Apart from this, chronic stress can lead to increased levels of cortisol and other stress hormones in the body that can promote cancer growth and its spread to various parts of the body. A constant state of stress can also weaken the immune system's ability to effectively fight off cancer cells. However, Dr Cuomo believes that there are ways to break free from all addictions and prevent cancer development in the body. He told 'The real threat is not a single cocktail or slice of cake. It is the craving that drives you back again and again. 'That craving is what wears down your body's defenses. I tell people to test their control. 'Start with one week of abstention. Not forever. Just seven days. That short reset reveals a lot. 'You learn what your body depends on. During that time, focus on physical recovery. Sleep deeply. Move your body. Eat real food. 'Spend time with people you trust. Addiction thrives in isolation. Recovery begins with reconnection.'

The Boys star Erin Moriarty reveals she's fighting the same autoimmune disease as Wendy Williams
Erin Moriarty gave a health update to her fans and revealed that she is currently battling an autoimmune disorder called Graves' disease. The Boys actress, 30 - who quit social media amid plastic surgery allegations last year - jumped to Instagram this week to get candid with her 2 million followers about her own 'experience.' The star uploaded a series of snaps, which included selfies and other moments from her life in recent months. 'Autoimmune disease manifests differently in everybody/every body,' Moriarty penned in the caption. 'Your experience will be different from mine. My experience will be different from yours. Perhaps greatly, perhaps minutely. 'One thing I can say: if I hadn't chalked it all up to stress and fatigue, I would've caught this sooner. A month ago, I was diagnosed with Graves' disease.' Wendy Williams is another celebrity who has been open about her battle with the autoimmune disorder, as well as Daisy Ridley and Missy Elliott. The disease is caused by an overproduction of thyroid hormones - with some symptoms being fatigue, bulging eyes, heart palpitations, and anxiety, per Mayo Clinic. Erin explained that following the diagnosis, she began undergoing treatment for her symptoms which has turned her life around. 'Within 24 hours of beginning treatment, I felt the light coming back on. It's been increasing in strength ever since.' In conclusion, the actress encouraged on getting health checks and wrote, 'If yours is dimming, even slightly, go get checked. Don't "suck it up" and transcend suffering; you deserve to be comfy. S**t's hard enough as is.' In some of the selfies included in the post, Moriarty flashed small smiles towards the camera while other images showed her looking tired. Erin further showed her struggles with symptoms in text message conversations she previously had with her parents. While talking to her mom, the actress had typed out: 'I'm serious; I really really need relief. I feel nauseated tonight. I feel so s**t and removed from who I am, I can't live like this forever. Or that long. 'There aren't moments anymore, not even a passing 5 seconds, when I feel normal. I've never had that. Not one.' 'Autoimmune disease manifests differently in everybody/every body,' Moriarty penned in the caption. 'Your experience will be different from mine. My experience will be different from yours. Perhaps greatly, perhaps minutely' Wendy Williams is another celebrity who has been open about her battle with the autoimmune disorder, as well as Daisy Ridley and Missy Elliott; Williams seen in 2019 in NYC Erin further showed her struggles with symptoms in text message conversations she previously had with her parents Moriarty had emotionally added, 'It's not just fatigue - it's an ineffable, system wide cry for help and I don't know how long I can remain in this state.' She also shared a screenshot of a text that she sent to her dad seemingly after she had started treatment. It read: 'I already feel a world of a difference, primary thought (as of now): "d**m, this is how I'm supposed to feel? I've been missing out!" xx.' Erin is known for her role in the Amazon Prime Video series The Boys as Annie January/Starlight. She has also starred in other shows including Marvel's Jessica Jones, True Detective and Red Widow. Moriarty has appeared in a number of films over the years such as The Kings Of Summer, Captain Fantastic and Catching Dust. Earlier last year in January, the actress notably quit social media after Megyn Kelly accused her of being 'obsessed' with plastic surgery. Kelly had stated at the time, 'She's got the Kim Kardashian lips, she's made her nose so skinny, it looks like a pencil now... I find it like a sign of mental illness.' Megyn also added, 'She's got, like, what appear[s] to me to be cheek implants. More and more young women are doing this. 'It's not about an objection to plastic surgery, it's about an obsession with turning yourself into this fake version of yourself... I find it like a sign of mental illness. 'It's extremely upsetting. It's just a massive turnoff to me. I really want to get in the heads of these young girls and say, "Please don't do this."' In response, Moriarty penned a lengthy statement while also announcing that she would be taking taking an 'extensive, if not permanent' break from Instagram. Erin wrote to her fans, 'The only reason I have not deactivated my account is because I will be leaving this here. Otherwise, consider it deactivated. I will not have access to it for an extensive if not permanent break. 'Social media is not something that came naturally to me and that was an investment of energy to connect with you guys.' The actress said she was 'horrified by the reaction, the reductive assumptions, and the aforementioned video [of Kelly's comments] that is a primary example of such harassment. 'It's broken my heart. You've broken my heart. You've lost the privilege of this account.' In response, Moriarty penned a lengthy statement while also announcing that she would be taking taking an 'extensive, if not permanent' break from Instagram Moriarty continued, 'The way that this has been spoken about, the way that I have been spoken to, I will not accept. I have been in a hole and I've been consumed by this personal situation at hand. 'You never know what someone is going through, social media is a platform that is not representative of a whole person, and irregardless there is no excuse for the words that have been spoken directly to me or about me.' The star explained at the time that she had recently undergone a stressful time which resulted her in losing weight. 'You learn to become Teflon and move on - I had NO idea what was going on this time. 'To receive a message about a disgustingly false, counterproductive to the degree of being ironically misogynistic video of Megyn Kelly commenting on the manner - to learn the widespread nature of this has left me horrified.' She also added, 'How utterly misinformed, inaccurate, and clickbait seeking people who we follow and consider to be informed is appalling...' Not long after leaving social media, the actress was seen in Los Angeles for a solo outing.

NHS patients battling Alzheimer's WON'T be offered 'miracle' drugs as health watchdog rules they are 'too expensive to justify'
Two of the first drugs proven to slow down Alzheimer's disease will be denied to NHS patients from this week - unless they pay to go private. The National Institute for Health and Care Excellence (NICE) has refused the 'miracle' drugs lecanemab and donanemab for use on the NHS as they are too expensive to justify. This means over 70,000 patients in England will be denied the 'game-changing' drugs, found to slow cognitive decline by an average of four to seven months, unless they can afford tens of thousands of pounds a year for private treatment. After a positive drug trial in 2022, lecanemab (brand name Leqembi) made by Eisai, and donanemab (marketed as Kisunla), made by Eli Lilly, were proven to clear toxic amyloid protein from the brain and thus slow the underlying cause of dementia. Campaigners hailed it as 'the beginning of the end' of Alzheimer's. Iain Hartnell, Research Communications Officer at Alzheimer's Society, said: 'The MHRA's approval of the first safe and effective Alzheimer's disease treatment, shown to slow progression, is a defining moment for people with early-stage Alzheimer's disease in the UK and a significant step towards a more hopeful future.' Last year, both drugs were given drug licences in the UK by the Medicines and Healthcare products Regulatory Agency (MHRA). But without NICE's recommendation, the groundbreaking medicine will only be available to those with private healthcare. 'It is the end of the road for these drugs on the NHS,' an insider told The Times. Hilary Evans-Newton, the chief executive of Alzheimer's Research UK described the decision as 'deeply disappointing'. She told the publication that it sends 'a damaging signal to the life sciences sector - undermining confidence in the UK as a leader of dementia research, clinical trials and innovation, with knock-on effects for patients and the wider economy'. She added: 'These treatments are not perfect, and we recognise the challenges they pose around cost, delivery and safety. But scientific progress is incremental, and these drugs represent a vital foundation to build on.' The drugs were shown in trials to slow the rate of decline for those with mild to moderate Alzheimer's by an average of four to seven months. Lecanemab, for example, can slow the decline in memory and mental agility by 27 per cent in those with mild Alzheimer's taking the drug compared to people on the dummy drug. The research team also found that the drug reduced loss of quality of life by up to 56 per cent, according to the Alzheimer's Society. Importantly, the drug reduced the amount of amyloid protein present in the brain. Amyloid protein levels were also reduced in the blood and spinal fluid. Experts have long believed donanemab could herald a new era of dementia treatment, after studies showed it slowed the memory-robbing illness in its early stages Lecanemab has already been given the green light in the EU, US, China, Japan, Hong Kong, South Korea and Israel. It is estimated around 70,000 adults in England could eligible for the treatment if approved for use on the health service. Alzheimer's is the most common cause of dementia in the UK. Around 982,000 are currently estimated to be living with dementia UK - although this figure is expected to skyrocket to 1.4million in 2040. Alzheimer's Research UK analysis found 74,261 people died from dementia in 2022, compared to 69,178 a year earlier, making it the country's biggest killer. Recent analysis by the Alzheimer's Society estimates the overall annual cost of the dementia to the UK is £42billion a year, with families bearing the brunt. An ageing population means these costs — which include lost earnings of unpaid carers — are set to soar to £90billion in the next 15 years.
