We’ve all heard the joke at some point — women take longer in the bathroom because they “pee more.” But is there any truth behind this bathroom stereotype? As it turns out, science is more complex than that, and the answer lies deep within the structure of our kidneys.

Biologically speaking, men generally have larger kidneys than women. But does that mean they produce more urine? Not necessarily.

A recent review of autopsy data has revealed some interesting findings. While men do tend to have physically larger kidneys, researchers aren’t entirely sure if this difference holds up once body size — such as height, weight, or body surface area (BSA) — is taken into account. In other words, just because a man has a bigger kidney doesn’t automatically mean it's more efficient or produces more urine.

Size Doesn’t Always Equal Output

Kidneys are vital organs responsible for filtering waste from the blood and maintaining fluid balance. Each kidney contains roughly a million nephrons — tiny filtering units that help produce urine. The number of nephrons is believed to be associated with kidney size. So, in theory, larger kidneys might have more nephrons and a higher filtering capacity.

However, here's where it gets interesting: When kidney size is adjusted relative to body size, men may not actually have significantly larger kidneys than women. And in clinical settings, women often show better kidney health outcomes over time. Studies suggest that women are less likely to develop or progress to chronic kidney disease (CKD), even though they may report more frequent urination.

So Why Do Women Feel the Urge More Often?

The frequency of urination is influenced by several factors beyond kidney size — including bladder size, hormone levels, fluid intake, and even societal behavior. On average, women have slightly smaller bladders than men, which means they may feel the need to urinate more often, especially when consuming the same amount of fluids.

Hormonal fluctuations during menstruation, pregnancy, or menopause also play a significant role in urinary patterns. Estrogen, for instance, affects the urinary tract and can make women more sensitive to the urge to go.

What It All Means

So, do women pee more than men? It depends. While they may urinate more frequently due to bladder size and hormonal factors, this doesn’t necessarily mean they produce more urine overall. The larger kidneys in men may be more efficient, but that doesn’t equate to more trips to the restroom.

Ultimately, urination is a deeply personal — and variable — experience. If you find yourself making more frequent bathroom visits than usual, regardless of gender, it might be worth discussing with a healthcare provider.

Because when it comes to your health, every drop matters.

Breast cancer is now the most commonly diagnosed cancer among women in India, representing a significant and growing public health concern. According to recent estimates, India recorded approximately 221,757 new breast cancer cases in 2022, making breast cancer the most common cancer among women and accounting for nearly one-fourth of all female cancers in several urban populations1.

Rising urbanisation, lifestyle changes, delayed childbirth, and increasing life expectancy have contributed to the growing incidence. Despite advances in awareness and screening, many women continue to be diagnosed at later stages, underscoring the need for effective, accessible, and patient-centric treatment approaches.

Moving Beyond One-Size-Fits-All Radiation Therapy

As cancer care evolves towards more personalised treatment, brachytherapy is emerging as a targeted alternative that delivers radiation with greater precision.

How Brachytherapy Delivers Radiation Where It Matters Most

Unlike conventional radiation, which passes through normal tissues before reaching the target, brachytherapy focuses treatment directly on the tumour bed. This precision helps maximise treatment effectiveness while reducing potential side effects.

A More Personalised Approach to Breast Cancer Treatment

One of the most significant applications of breast brachytherapy is Accelerated Partial Breast Irradiation (APBI). In selected patients with early-stage breast cancer, the risk of recurrence is highest around the original tumour site. APBI targets only this region rather than treating the entire breast.

This focused approach helps protect healthy breast tissue and nearby organs such as the heart and lungs. Advanced imaging and treatment-planning technologies further enhance personalisation by allowing radiation doses to be tailored to the patient's anatomy and tumour characteristics.

Shorter Treatment Duration, Greater Convenience

A major advantage of brachytherapy is the shorter treatment schedule it offers. Conventional radiation therapy may require daily sessions for three to six weeks, whereas brachytherapy-based APBI can often be completed within a few days.

For patients travelling long distances to access specialised cancer care, this can reduce both the logistical and financial burden of treatment while minimising disruptions to daily life.

Preserving Quality of Life After Cancer

As survival rates improve, quality of life has become a key consideration in breast cancer care. Brachytherapy's targeted approach reduces radiation exposure to healthy tissues and has been associated with favourable cosmetic outcomes.

By combining precision, convenience, and effectiveness, brachytherapy represents an important step towards personalised breast cancer treatment, offering appropriately selected patients an opportunity for effective care with potentially fewer side effects and improved overall treatment experience.

Bryan Johnson Reveals Meibomian Gland Dysfunction: What To Know About This Dry Eye Condition

Updated Aug 19, 2026 | 11:29 AM IST

SummaryMGD can remain asymptomatic during its initial stages. When symptoms appear, the condition can resemble ordinary dry eye, allowing it to worsen and lead to permanent gland dropout.

Longevity expert and multi-billionaire Bryan Johnson has revealed another health condition affecting him. This time, it is meibomian gland dysfunction (MGD).

Johnson also said that the largely asymptomatic condition affects nearly 90 percent of adults over 40. The condition can "lead to permanent eye damage" and also affects younger people because of increased exposure to screens.

“I just learned that I have meaningful meibomian gland dropout. This is why my eyes are irritated,” Johnson said in a post on social media platform X.

“The dropout leads to evaporative dry eye disease, which triggers vision degradation such as blurred text, glare at night, light sensitivity, and neuropathic ocular pain. Left long enough, it can scar the cornea and permanently damage vision,” he added.

What Is Meibomian Gland Dysfunction?

Meibomian gland dysfunction happens when the tiny oil glands in the eyelids become blocked or produce poor-quality oil. This prevents enough oil from reaching the tears, causing them to dry up too quickly.

Major triggers include aging, hormonal shifts, screen use, and skin or eye inflammation, according to Cleveland Clinic.

Johnson explained that there are about “60 meibomian glands per eye, split across the upper and lower lid. They are like pores, secreting nourishing oil (meibum) onto your tear film to prevent rapid evaporation.”

He noted that the glands can become dysfunctional due to conditions or factors including "age, androgen deficiency, menopause, hormone replacement, oral contraceptives, isotretinoin, antihistamines, SSRIs, tricyclics, beta blockers, diuretics, anticholinergics, preserved eye drops, incomplete blinking, reduced blink rate, screen use, contact lens wear, and ocular rosacea".

When these glands become clogged, the meibocytes can die, and the gland can eventually drop out. Johnson said conventional medicine considers total gland dropout irreversible.

Why Can MGD Go Unnoticed?

Importantly, Johnson said that MGD can remain asymptomatic during its initial stages. When symptoms appear, the condition can resemble ordinary dry eye, allowing it to worsen and lead to permanent gland dropout.

Advanced MGD can also numb the cornea, further masking subjective symptoms as the disease progresses.

How Did Bryan Johnson Detect MGD?

Johnson's MGD was detected after he went to the doctor for a chalazion or stye, a painful, red bump on the edge of the eyelid.

He also mentioned undergoing diagnostic tests, including the Schirmer test and infrared meibography.

How Is Johnson Treating MGD?

Johnson began treatment with in-office intense pulsed light (IPL), radiofrequency (RF), and an experimental intraductal probing, known as the Maskin protocol, to address inflammation and physically reopen clogged glands.

The eye-light device combines IPL with 630-nm red low-level light. The proposed mechanism involves stimulating mitochondrial ATP production in meibocytes and reducing inflammation around the eyes.

The probing therapy involved using 1-mm, 2-mm, and 4-mm probes, which were inserted into each gland orifice.

“My doctor then expressed my glands, using a roller device to expel any buildup and kickstart the gland’s natural expression. This is really painful. Brings you to tears,” Johnson said.

Along with IPL, RF, and probing, he was also using warm eye compresses twice a day, in the morning and at night.

“With this protocol, we’ve seen a 30% improvement in meibomian gland function (using imaging). My glands look healthier, eye irritation has lessened, my subjective symptoms have subsided, and when we probe now, we encounter minimal fibrotic resistance (popping),” he said.

Signs of MGD to Watch For

Johnson listed several symptoms and warning signs to watch for, including:

  • Burning or a gritty sensation in the eyes
  • Vision that blurs and then clears when you blink
  • Watery eyes, as dryness can trigger reflex tears
  • Red, crusty or bumpy eyelid margins
  • Recurring styes
  • Contact lenses becoming uncomfortable
  • Symptoms worsening when using screens, travelling on planes or staying in air-conditioned environments

Any of these symptoms, particularly after age 40, may warrant a gland examination, Johnson said.

August 18 marks World Breast Cancer Research Day, a day that reminds us that every major breakthrough in cancer care has its roots in research. The medicines that are prescribed, the diagnostic technologies that we use, the targeted therapies that we offer and our growing understanding of why cancers develop and spread, are all outcomes of regular scientific research.

India carries one of the world's largest cancer burdens. According to IARC's GLOBOCAN 2022 estimates, India recorded approximately 1.41 million new cancer cases and more than 916,000 cancer deaths in 2022. Breast cancer alone was the leading cancer among Indian women and also the leading cancer overall.

India as a country, has a large and diverse patient population, significant clinical expertise, strong medical institutions and a pharmaceutical industry with enormous manufacturing capabilities. But there is a crucial gap between manufacturing what the world has already discovered and researching newer medical opportunities.

A significant proportion of cutting-edge cancer research continues to emerge from countries with substantially larger and more established research ecosystems. When scientific discoveries, new molecules, diagnostic technologies or treatment approaches are developed elsewhere, Indian patients benefit from them at a later stage.

We Need To Move Beyond A Few Centres Of Excellence

We have limited institutes that have made important contributions to cancer care and research. But considering India's population and cancer burden, the scale of research infrastructure needs to expand substantially. We need more dedicated cancer-research institutes, stronger university hospital industry collaborations, modern laboratories, biobanks, genomic databases, data-science capabilities and trained physician-scientists.

Cancer is not just one disease. It comprises of multiple biological subtypes, and the way a tumour behaves can vary significantly between individuals and populations. Therefore, India needs research that focusses specifically towards Indian patients.

Clinical Trials Can Be Part Of The Solution

India has a formal Clinical Trials Registry, and the registry currently records more than 100,000 trials across areas of medicine.

For eligible patients, participation in an appropriate clinical trial may provide access to an investigational therapy or treatment strategy that is not yet routinely available. Clinical trials generate evidence that can improve future treatment for thousands or millions of patients.

Research Needs To Become A Policy Priority

We need to create an ecosystem that moves from discovery to translation to patient care. That means incentivizing research institutions and researchers, supporting young physician-scientists, strengthening public-private partnerships and making it easier for promising discoveries to move from laboratories into clinical development.

We need to have an ecosystem, where healthcare research, particularly research addressing diseases with an enormous Indian burden should receive a much greater and more targeted share of national research investment. A large, diverse population can generate valuable real-world evidence. Large patient cohorts can help researchers understand disease patterns. Indian genetic and molecular data can help answer questions that may not be adequately addressed through studies conducted in other countries.

From Manufacturing Medicines To Discovering The Next Generation Of Treatments

India has already demonstrated that it can serve the world as a pharmaceutical manufacturing powerhouse. We should look at also becoming the research hub for the world by combining our pharmaceutical manufacturing strength, clinical expertise, technology capabilities and patient population.

The opportunity is already in front of us.

What we need now is the policy ambition to implement it.
