Sometimes the food you eat or the behavior you exhibit can be a sign of a deficiency and condition you may have. It is similar to when your stomach growls, which signifies that you are hungry. Other signs you may not know about are feeling fatigued when you do not drink enough water, and if you are experiencing a headache then you may need to eat etc. These things happen because they are connected in one way or the other, when you body lacks a specific nutrient you need throughout your day, it can manifest in different ways, let’s take iron for example.

Iron is like the delivery truck for oxygen in your body. It helps your red blood cells carry oxygen from your lungs to all your tissues. The Red Cross Blood Donation explains that when you don't have enough iron, your body can't make enough of these oxygen-carrying cells. This is called iron deficiency, and it can lead to anemia. You might feel very tired, look pale, or get dizzy easily. Headaches, cold hands and feet, and weak hair and nails are also common signs. Because iron is so vital for many of your body's functions, a lack of it can really affect your overall health and energy levels. It's important to recognize these signs and get checked by a doctor if you suspect you might have an iron deficiency.

What is Pagophagia and Pica?

Sometimes, your body sends strange signals when it's missing something important. One unusual signal for iron deficiency is wanting to eat ice, which doctors call pagophagia. This is part of a bigger problem called pica, where people crave things that aren't food. Other examples of pica are wanting to eat dirt, clay, or even starch. It's not just these things; some people crave things like coal, chalk, paper, or hair. While kids get pica more often, adults with low iron can have it too, even if they don't have anaemia. This weird craving is your body's way of trying to tell you something's wrong, even if it seems odd.

Eating things that aren't food can be risky. For example, eating dirt could expose you to harmful germs or heavy metals. Eating large amounts of ice might not seem dangerous, but it can sometimes hurt your teeth or gums. Ingesting non-food items can lead to serious problems like poisoning, where harmful substances build up in your body. It can also cause blockages in your intestines, which can be very painful and dangerous. Symptoms like stomach pain, bloating, feeling very tired, nausea, and diarrhea can signal that something is wrong. If you find yourself constantly wanting to eat ice or other non-food items, it's really important to talk to a doctor. They can help figure out why you're having these cravings and make sure you stay safe.

How Can You Make This Better?

If you're craving ice or other non-food items, it's important to see a doctor. They'll ask about your symptoms and might do some blood tests to check your iron levels. It's possible that your cravings are caused by iron deficiency, but they could also be related to other nutritional deficiencies or even emotional problems. Things like stress, obsessive-compulsive disorder, or developmental issues can sometimes cause pica. The doctor will try to figure out the root cause of your cravings. If it's an iron deficiency, they might suggest taking iron supplements or changing your diet. If it's an emotional issue, they might recommend talking to a therapist. Getting the right diagnosis and treatment is important for your health and well-being.

Hormonal changes during menopause can significantly increase Alzheimer's disease (AD) risk in women, according to Dr Lisa Mosconi, a neuroscientist and women’s brain health specialist.

In a new The Journal of Clinical Investigation review, the renowned AD expert noted that menopause can change brain biology and metabolism and may contribute to amyloid plaques and tau tangles, which are key biological markers of AD.

Alzheimer disease is the most common cause of dementia, affecting over 55 million individuals worldwide, with projections exceeding 150 million by 2050 . Out of the reported cases, nearly two-third are made up of women, with the majority being postmenopausal women

Estrogen protects the brain by lowering inflammation, increasing neuronal survivals supporting non-amyloidogenic processing, and reducing amyloid-beta-related neurotoxicity, all of which are factors contributing to the development of AD.

However, when estrogen levels drop during menopause and follicle-stimulating hormone (FSH) and luteinizing hormone (LH) rise, the brain becomes more likely to develop AD-related damage.

Previous research has also shown that early menopause, especially before age 45, is linked with increased risk of dementia and the removing the ovaries before natural menopause could increase long-term dementia risk, with the greatest excess risk seen at younger ages, especially before 45.

What Is Alzheimer’s Disease?

Alzheimer's disease is one of the most common forms of dementia and mostly affects adults over the age of 65.

About 8.8 million Indians aged 60 and above are estimated to be living with Alzheimer's disease. Over seven million people in the US 65 and older live with the condition and over 100,00 die from it annually.

Alzheimer's disease is believed to be caused by the development of toxic amyloid and beta proteins in the brain, which can accumulate in the brain and damage cells responsible for memory.

Amyloid protein molecules stick together in brain cells, forming clumps called plaques. At the same time, tau proteins twist together in fiber-like strands called tangles. The plaques and tangles block the brain's neurons from sending electrical and chemical signals back and forth.

Over time, this disruption causes permanent damage in the brain that leads to Alzheimer's disease and dementia, causing patients to lose their ability to speak, care for themselves or even respond to the world around them.

While there is no clear cause of Alzheimer's disease, experts believe it can develop due to genetic mutations and lifestyle choices, such as physical inactivity, unhealthy diet and social isolation.

Early symptoms of Alzheimer's disease include forgetting recent events or conversations. Over time, Alzheimer's disease leads to serious memory loss and affects a person's ability to do everyday tasks.

There is no cure for this progressive brain disorder and in advanced stages, loss of brain function can cause dehydration, poor nutrition or infection. These complications can result in death.

Can You Detect Alzheimer's Early On?

The US Food and Drug Administration has approved the use of a blood test which can help diagnose Alzheimer’s disease in adults aged 55 and above.

The blood test, known as Lumipulse, can detect amyloid plaques associated with Alzheimer’s disease and has proven to be a “less invasive option” that “reduces reliance on PET scans and increases diagnosis accessibility.”

FDA Commissioner Martin A. Makary said of the landmark decision, "Alzheimer’s disease impacts too many people, more than breast cancer and prostate cancer combined.

"Knowing that 10 percent of people aged 65 and older have Alzheimer's, and that by 2050 that number is expected to double, I am hopeful that new medical products such as this one will help patients."

It remains unclear when this test will be available for commercial use across the world.

While GLP-1 drugs like Ozempic are popular for weight loss, a new study published today in The Lancet Psychiatry journal showed that it can also help tackle the burden of depression, anxiety, and self-harm in high-risk diabetic patients.

The GLP-1 drugs, with ingredients such as semaglutide and liraglutide, were found to effectively reduce the risk of these mental health conditions in patients already taking the medications to manage their diabetes or obesity.

The study found that these medications were linked to

• fewer psychiatric hospitalizations,
• taking sick leave due to mental illness,
• death by suicide.

The study comes as people with diabetes are known to have a higher risk of depression (2-3 times), anxiety (20 percent), and suicide than the general population.

“Our findings suggest that GLP-1 drugs, particularly semaglutide, might contribute to better mental health in people with diabetes and obesity,” said Jari Tiihonen, specialist physician and professor at the Centre for Psychiatry Research, Karolinska Institutet, Sweden.

Calling the results "observational", Tiihonen urged the need for controlled clinical trials to confirm the findings.

Key Findings

The researchers followed more than 95,000 participants diagnosed with depression or anxiety and were prescribed various antidiabetic medications through Swedish national registers between 2009 and 2022. Of the patients, 22,480 had used GLP-1 drugs.

Semaglutide, the main ingredient in Ozempic, showed the highest benefits against the mental health conditions. Semaglutide led to a:

• 42 percent reduced risk of worsening mental health
• 44 percent lower risk of worsening depression,
• 38 percent lower risk of worsening anxiety,
• 47 percent lower risk of worsening substance use disorder.

On the other hand, liraglutide, sold under the brand names Victoza (for type 2 diabetes) and Saxenda (for chronic weight management), was linked to an 18 percent lower risk of worsening mental health.

Other GLP-1 medications, including exenatide and dulaglutide, did not show the same benefit.

How Do GLP-1 Medicines Fight Against Addiction?

A recent study, published by researchers at the Washington University School of Medicine in St Louis, reported that Ozempic could prevent substance use disorder and could also treat it.

Not just the lack of will to eat food, but some people have actually reported a lack of interest in alcohol or nicotine consumption.

Previously, observational studies have also shown how it could lower the risk of alcohol and cannabis use disorders, opioid overdose, and alcohol related hospitalization.

The findings published in The BMJ showed that people taking GLP-1 drugs had a 14 percent lower risk of developing any substance use disorder.

Their substance-specific reductions:

• Alcohol use disorder risk fell by 18 percent
• Cannabis use disorder fell by 14 percent
• Cocaine and nicotine use disorders fell by 20 percent
• Opioid use disorder fell by 25 percent

Digestive problems like bloating, gas, acidity, and constipation have quietly become a common problem in our daily lives. It is common these days to find people experiencing discomfort after meals or feeling unusually heavy. While these problems may not be serious in nature, doctors say these problems have increased in recent times due to changes in the way people live and eat.

• The first major cause of these problems in recent times is the change in the way people eat. It is a known fact that people are now eating more of junk food and less of fiber-rich food. Fiber plays a crucial role in keeping digestion smooth and bowel movements normal. If the amount of fiber in the diet is low, digestion becomes slow, leading to bloating, gas, and constipation.

• Another major cause of these problems in recent times is the sedentary lifestyle people are leading these days. It is a known fact that a person should move around a lot in a day. Lack of physical activity may cause problems in digestion. Simple habits like eating quickly, missing meals, or drinking excessive carbonated beverages are some of the common causes of excessive gas and discomfort.

• Another cause of digestive upsets that is often overlooked is stress. The fact that the brain and digestive system are closely related means that digestive upsets can be caused by emotional stress. When a person is under a lot of stress, hormones are secreted into their system that can slow down digestion. As a result, a person may feel stomach upsets like tightness, bloating, irregular bowel movements, or even develop a medical condition like irritable bowel syndrome depending on their digestive system composition.

• In addition to that, other lifestyle habits like late-night meals, lack of proper sleep, dehydration, or excessive caffeine intake can cause digestive upsets. When a person’s body is out of sync, digestion is not as effective as it should be. As a result, food ferments in the stomach, leading to excessive gas production.

Traditional Remedies

Most people tend to use various remedies when they are feeling unwell.

Remedies such as the consumption of warm water, fennel seeds, ginger tea, and the intake of probiotics in the form of curd may offer temporary relief. However, it is important to note that these might offer temporary relief and might not be effective if the symptoms of digestive discomfort are recurring.

Digestive discomforts that recur frequently should not be taken lightly. Frequent occurrences of digestive discomforts such as bloating and constipation might sometimes be symptoms of an underlying condition.

Therefore, if the symptoms of digestive discomfort last for weeks and if the symptoms also include the presence of any of the aforementioned symptoms of digestive discomfort, it might be important to consult a doctor.

Gut Problems: Need For Lifestyle Modifications

The relationship between gut health and wellbeing is also well noted. Among the lifestyle modifications that may be implemented for improved digestive health is a healthy and balanced diet, exercising regularly, adequate intake of water, stress levels, and eating at regular times.

It is a normal occurrence for people to experience bloating and gas at some point in their lives. However, if discomfort in the digestive system is a frequent occurrence, it may be a wake-up call from the body that something is amiss and deserves attention. Heeding such a call and making lifestyle modifications may work wonders for the gut.
