Your skin is often considered a reflection of your body's inner wellbeing, when it comes to kidney function, the connection goes beyond what may initially be something on the surface. The kidneys are responsible for filtering out wastes and toxins in the blood, balancing electrolytes, and helping to control moisture levels. Once kidney function breaks down, its effects are felt not only overall but also are reflected in discernible skin-related changes—dryness, pigmentation, long-term itching, and even hives.

But when the kidneys are unwell, they do not just impair internal function but also manifest themselves on the outside, and specifically on the skin. In the opinion of Dr. Sreedhar Reddy, Urologist and Urology Surgeon, "Kidney-related ailments frequently cause palpable changes to the skin, which may act as preliminary signals for renal illness."

Link Between Your Kidney Health and your Skin

When the kidneys do not effectively remove waste products and excess water from the body, toxins in the blood buildup. This accumulation manifests as several dermatological manifestations indicating intrinsic renal disease. These are:

Xerosis (Severe Dryness of the Skin): Patients can have very dry, rough, scaly skin, which is usually accompanied by cracking. Dr. Reddy describes, "Extremely dry skin that is tight and tends to crack is frequently seen in patients with end-stage kidney disease who are on dialysis or need a transplant."

Pruritus (Itchy Skin): Itching is one of the most common symptoms of kidney disease. A recent survey of individuals on hemodialysis found that 61% reported experiencing at least a moderate level of itching, with 25% describing it as "very" or "extremely intense." This persistent itch occurs as waste products accumulate in the blood, irritating nerve endings.

Pigment Disorders and Rashes: Inability of the kidneys to function properly can cause the accumulation of metabolic byproducts in the skin, causing color changes and rashes. "Dome-shaped, intensely itchy rashes tend to mean that the kidneys are not clearing toxins well," adds Dr. Reddy.

Effect of Kidney Disease on Overall Appearance

Aside from skin disorders, kidney disease has an effect on a person's overall appearance because of metabolic disturbances and fluid imbalance.

Weight Changes: Kidney disease may result in sudden weight loss from muscle atrophy or sudden weight gain from fluid buildup. "Patients tend to develop swelling of the face, hands, and feet because of too much fluid," explains Dr. Reddy.

Changes in Skin Texture and Color: Kidney impairment can result in pallor, yellowish or grayish complexion, and a dull skin.

Hair and Nail Changes: Thin hair, ridges, and brittle nails are reported by many patients with chronic kidney disease (CKD).

Kidney Disease and Its Link to Other Health Conditions

Some other health disorders linked with kidney disease can cause skin conditions and changes in appearance:

Diabetes and Hypertension: Diabetes and hypertension are major causes of kidney disease, and both diseases can worsen skin conditions like itching and delayed healing of wounds.

Liver Dysfunction: A dysfunctional liver, usually associated with kidney problems, can cause bile salts to pile up beneath the skin, which may cause intense itching.

Blood Diseases and Autoimmune Disorders: Certain cancers, thyroid disease, and autoimmune disorders such as celiac disease may also lead to long-term itching secondary to systemic inflammation and nerve stimulation.

How to Keep Your Kidneys Healthy?

For those of us who care about our skin and our well-being, ensuring that our kidneys are functioning properly is important. Dr. Reddy stresses that making some small lifestyle adjustments can greatly enhance kidney health and stave off overt skin decline.

1. Have a Kidney-Friendly Diet

Reducing the intake of sodium, phosphorus, and potassium while increasing antioxidant-rich foods can protect kidney function and enhance skin health.

2. Stay Hydrated

Adequate water intake helps flush out toxins, reducing the burden on the kidneys and preventing dryness and irritation in the skin.

3. Exercise Regularly

Physical activity improves circulation, enhances waste elimination, and supports overall metabolic function.

4. Avoid Smoking and Excessive Alcohol Consumption

Tobacco and alcohol also add to kidney stress, resulting in fluid buildup and inflammation that may adversely affect the skin.

5. Routine Health Checkups

Routine tests of blood pressure, blood sugar levels, and kidney function may help identify early evidence of kidney disease, averting severe complications.

When to Consult A Doctor?

Early warning signs of kidney disease can be identified and avoided in order to prevent severe complications. If you suddenly notice unexplained itching, a chronic rash, extreme dryness, swelling, or a great weight gain, seek advice from a health expert. Kidney function can be tested by conducting blood tests that eliminate other health conditions like diabetes, anemia, or thyroid disorders.

Your kidneys are also responsible for detoxification, the balance of fluid, and metabolism. When compromised, the effects are not only internal but also evident on your complexion and overall look. By living healthy, keeping an eye on kidney function, and consulting a doctor when needed, one can have healthy kidneys along with maintaining healthy skin's natural sparkle and radiance. Dr. Reddy affirms, "Healthy kidneys mean healthy skin. Paying attention to both can improve overall well-being and quality of life."

A new weight-loss drug often described as the “triple G” treatment because it mimics three hormones linked to hunger and metabolism has delivered striking results in fresh data shared Thursday by its developer, Eli Lilly. In a clinical study involving more than 400 people living with obesity and knee osteoarthritis, the experimental drug retatrutide led to an average weight reduction of 71 pounds, or close to 29% of total body weight, over a period of 16 months, according to figures released by the company. Participants who received retatrutide also reported a 76% drop in knee pain by the end of the study period, based on the same data. So is

What Is Retatrutide?

Retatrutide is an experimental weight-loss drug developed by Eli Lilly and is widely seen as a next-step advancement beyond current GLP-1-based medications such as semaglutide and tirzepatide. While semaglutide acts on a single hormone pathway and tirzepatide works on two, retatrutide targets three.

It activates GLP-1 and GIP, along with an added glucagon pathway, which is why it is sometimes informally referred to as a “GLP-3” drug. Researchers believe this third pathway could explain the greater weight-loss effects seen so far, although retatrutide remains under investigation and has not yet received FDA approval.

Why Is Retatrutide Trending?

Even without regulatory approval, retatrutide has gained attention among gym enthusiasts, fitness creators, and online weight-loss communities. On platforms like TikTok, where direct searches for #reta or #retatrutide are restricted, users often refer to it using coded terms such as “ratatouille.”

At the same time, the drug has been in the news due to growing concerns about counterfeit versions. Reports from the UK recently revealed that authorities seized more than £250,000 worth of fake weight-loss injection pens labelled as tirzepatide and retatrutide from a hidden factory in Northampton. These products are especially concerning because retatrutide is still in clinical trials and has not been approved for use anywhere in the world.

How Is Retatrutide Different Than Other Weight-Loss Drugs?

Retatrutide works by mimicking three hormones that play a role in appetite and metabolism: GLP-1, GIP, and glucagon. In contrast, most weight-loss drugs currently available target only one or two of these pathways. Ozempic and Wegovy, made by Novo Nordisk, copy the effects of GLP-1, a hormone that influences the brain, pancreas, stomach, liver, and muscles, according to the National Institutes of Health.

Mounjaro and Zepbound, on the other hand, act on both GLP-1 and GIP, a hormone involved in blood sugar regulation through insulin stimulation. Retatrutide’s added glucagon effect is key, as glucagon is known to support fat burning, even when the body is at rest. Ozempic and Mounjaro are approved by the FDA for treating Type 2 diabetes, while Wegovy and Zepbound are approved for people with overweight or obesity. As with any prescription drug, it is important for individuals to consult a healthcare professional to determine whether these treatments are appropriate for them.

When Is Retatrutide Expected To Be Available To Consumers?

There is currently no confirmed timeline for when retatrutide might become available by prescription. Its launch will depend on the FDA’s detailed evaluation of clinical trial data once it is formally submitted. Based on current expectations, approval is unlikely before late 2026 and could potentially extend into 2027 or even 2028.

The use of nicotine pouches is rising sharply across the UK, especially among young adults, recent research suggests. These small pouches sit between the lip and gum and release nicotine gradually into the body. Available in many flavours, they often include sweeteners and plant-based fibres. But are they truly a better option than smoking, or could nicotine pouches still pose health risks? We take a closer look below.

What Are Nicotine Pouches?

Nicotine pouches are small, tobacco-free sachets that contain nicotine powder along with flavourings and fillers. They are placed between the lip and gum, similar to snus, allowing nicotine to be absorbed without smoke, vapour, or spitting. Marketed as a discreet way to consume nicotine, they still deliver a highly addictive substance and expose users to certain chemicals. Health experts have raised concerns, particularly for young people, despite these products often being promoted as a “safer” choice than cigarettes.

Popular brands such as Zyn, On!, and Velo now dominate a fast-growing market, according to the CDC. Like vaping, they do not contain tobacco and are generally viewed as less harmful than smoking.

A recent study led by researchers at University College London (UCL) found that over the past five years, about 522,000 additional people in the UK have started using nicotine pouches, with usage rising from 0.1% to 1% of the adult population.

This has raised an important question: are nicotine pouches actually safer than smoking, and what is driving their sudden popularity?

Nicotine Pouches: Is Using Them Safer Than Smoking?

Speaking on *Mornings with Ridge and Frost*, lead study author Dr Harry Tattan-Birch from UCL’s Institute of Epidemiology and Health Care told Sky News that the risks linked to nicotine pouches are much lower than those associated with smoking. “There’s no tobacco and no combustion,” he explained. “And we know it’s the burning of tobacco that causes most smoking-related diseases.”

That said, Dr Tattan-Birch and his colleagues stressed that these products are not harmless and should never be accessible to children. The NHS notes that while nicotine itself does not cause serious diseases in the way tobacco does, young people’s developing brains and lungs are more vulnerable to its effects, and dependency can form quickly.

UCL research fellow Eve Taylor also told Sky News that nicotine pouches are “far less harmful than smoking,” but cautioned that they are still relatively new. Because of this, their long-term effects are not yet fully understood. “We can look at what’s in them to estimate potential risks,” she said. “They’re not risk-free. Users are still exposed to some toxic substances, even if the levels are much lower.”

Nicotine Pouches: Are Pouches Helping People Quit Smoking?

According to UCL’s findings, among participants surveyed between January 2022 and March 2025, 69% of nicotine pouch users were also using other nicotine products. More than half of them, 56%, were still smoking cigarettes. Around one in six users, or 16%, reported that they had never been regular smokers, suggesting the habit was not linked to quitting cigarettes.

As quoted by Sky News, Dr Tattan-Birch said the public health impact of nicotine pouches depends largely on who is using them. “If a young person who might otherwise smoke switches to pouches, that could reduce harm,” he said. “But if someone who wouldn’t have used nicotine at all starts using them, the risk of harm goes up.”

Researchers added that more studies are needed to understand whether nicotine pouches genuinely help people stop smoking in the long run.

Are Nicotine Patches Harmful For Health?

Nicotine patches are widely regarded as safer than smoking and are a well-established aid for quitting. They provide a steady dose of nicotine to reduce cravings without exposing users to tar or cancer-causing chemicals found in cigarettes. However, they are not completely without side effects. Common issues include skin irritation, headaches, and sleep disturbances. People with serious heart conditions or those who are pregnant are advised to speak with a doctor before using them, as nicotine can still affect heart rate and blood pressure, though far less dangerously than smoking, according to the CDC.

People have been advised not to rely on a commonly used medicine when dealing with flu or cold symptoms. The UK Health Security Agency (UKHSA) has released an important warning about the use of antibiotics. Antibiotics are drugs designed to treat bacterial infections. They work by killing bacteria or stopping them from growing and multiplying. But why are health authorities urging caution against antibiotics during the current rise in flu cases?

Flu Influenza: Super Flu Cases Rising In UK And US

This year, a new strain of influenza, known as influenza A H3N2 or the subclade K variant, is spreading quickly across several countries, including the United States, according to Fox News. This week, the Centers for Disease Control and Prevention reported an 8.1% increase in positive flu tests across the country.

The UK is facing a similar situation. The NHS has warned that hospitals in England are dealing with a “worst case scenario” this December due to a surge in so-called “super flu” cases. An average of 2,660 patients per day were hospitalised with flu during the first week of December, the highest number ever recorded for this time of year and a 55% jump from the previous week.

Flu Influenza: Why Is UKHSA Warning Against Taking Antibiotics During Super Flu?

Antibiotics are medicines specifically meant to fight bacterial infections by destroying bacteria or preventing them from spreading. This helps the body’s immune system clear the infection. However, it is important to understand that antibiotics do not work on viral infections. These include illnesses such as the common cold, flu, and COVID-19.

In a post shared on social media platform X, the UKHSA stated: “Antibiotics don’t work for colds and flu – pharmacists can advise you on how to treat your symptoms.”

Flu Influenza: Guidelines On Using Antibiotics During Super Flu

The UKHSA has urged people to follow a few “simple” rules when it comes to antibiotics:

• Don’t take them for colds or flu
• Don’t save them to use later
• Take them exactly as prescribed

This advice comes as flu cases continue to rise across the UK. Data from the UKHSA showed that in the week ending December 7, flu positivity in England increased, with the weekly average reaching 21 per cent, up from 17 per cent the week before.

Hospital admissions linked to flu also rose to 10.05 per 100,000 people, compared with 8.09 per 100,000 previously.

Flu Influenza: Antibiotic-Resistant Infections

The warning follows the publication of the UKHSA’s English Surveillance Programme for Antimicrobial Utilisation and Resistance (ESPAUR) report in November. The report revealed that around 400 people each week in England are diagnosed with antibiotic-resistant infections.

These infections are harder to treat and can result in serious health problems. Experts say that the excessive use of antibiotics over time has reduced their effectiveness, leading to the rise of so-called “superbugs.”

The NHS explains that these are types of bacteria that have developed resistance to several antibiotic treatments, including:

• MRSA (methicillin-resistant Staphylococcus aureus)
• Clostridium difficile (C. diff)
• The bacteria responsible for multi-drug-resistant tuberculosis

The NHS has warned: “These infections can be serious and difficult to treat, and are becoming an increasing cause of disability and death worldwide. The greatest concern is that new strains of bacteria could develop that cannot be treated with any existing antibiotics.”

Dr Alicia Demirjian, consultant epidemiologist and clinical lead for antimicrobial resistance and prescribing at the UKHSA, said: “Antibiotic resistance is one of the biggest threats to modern medicine, but the good news is that we can all help reduce it.”

When a GP prescribes antibiotics, it is vital to follow the instructions carefully and not miss any doses.

The NHS advises: “If you forget to take a dose of your antibiotics, check the patient information leaflet that comes with your medicine to see what to do. If you’re unsure, speak to a pharmacist or your GP.

“In most cases, you can take the missed dose as soon as you remember and then continue the course as normal. But if it’s nearly time for your next dose, skip the missed one and carry on with your regular schedule.” You should never take a double dose to make up for a missed one.
