PCOS affects a major part of a menstruating person’s life than many of them are aware of. The lack of information about the condition and the reluctance of people to talk about the matter makes it worse. As we kick off World PCOS Awareness Month, we try to understand the proper repercussions and the best ways to manage your periods. As science progresses each day, many women have taken the initiative to further the research on PCOS and the reproductive health of women. We spoke to Dr Prarthana Shah, a doctor who specialised in preventative CVD medicine and an Integrative Health Coach to get a better understanding of the vital role nutrition plays in a woman’s reproductive cycle.

Polycystic Ovary Syndrome (PCOS) is a hormonal disorder affecting millions of women worldwide. Characterized by irregular menstrual cycles, excess androgen production, and the presence of cysts on the ovaries, PCOS can lead to a range of health issues, including infertility, obesity, type 2 diabetes, cardiovascular disease, and endometrial cancer.

Role of Nutrition in PCOS Management

A balanced diet plays a crucial role in managing PCOS symptoms and reducing the risk of associated health complications. By focusing on nutrient-dense foods and avoiding certain triggers, women with PCOS can significantly improve their overall well-being.

According to Dr. Prarthana, “The first thing is B12. So, a common deficiency, even otherwise, which can affect a woman's hormonal balance, because it helps regulate your hair length, and so it's important to make sure that you're getting enough B12.” There are important nutrients that women must have for healthy menstrual cycles.

• Vitamin B12: Essential for hormonal balance, hair health, and regular menstruation.
• Vitamin D: Helps regulate hormones, supports ovarian function, and improves insulin sensitivity.
• Iron: Crucial for preventing anaemia, which is common during menstruation.
• Electrolytes: Help maintain fluid balance and prevent fatigue.
• Amino acids: Provide building blocks for proteins and support overall health.

Dietary Recommendations for PCOS

As Dr Prarthana mentioned, the key nutrients that women lack are the reason why their periods might be irregular and make it difficult for them to handle it. She suggested that it's essential to prioritize a nutrient-rich diet. Focus on consuming whole foods like fruits, vegetables, whole grains, lean proteins, and healthy fats.

Minimize your intake of processed foods, sugary drinks, processed meats, and refined carbohydrates, as these can contribute to inflammation and hormonal imbalances. Consider limiting or avoiding dairy products, as they may contain hormones that can disrupt your hormonal regulation.

She also emphasised the importance of seasonal fruits. While many people have expressed their reservations with cross-contamination and germs from fruits she says, “You have to eat seasonal fruits and vegetables. Greens and salad leaves, all of these things for vitamin B12. Now, of course, there will be some vendors that cut it up. So, don't buy it from there. one tip I personally suggest is that I use something called Veggie Wash where I wash my salad leaves in that at home. You can also wash it with salt or apple cider vinegar.”

When enjoying seasonal fruits and vegetables, be mindful of potential contamination from vendors who cut and sell them. Wash them thoroughly at home to ensure safety. Finally, stay hydrated by drinking plenty of water throughout the day to support overall health and prevent dehydration.

Lifestyle changes you should make for PCOS

According to Dr Prarthana, your lifestyle plays a really important role in PCOS, “So, I know most women, even though they regularly exercise, I mean the ones that do, also kind of skip it during the period and that is the wrong thing to do, ideally.”

She also expresses how much it actually helps with period pains and relief for women, “It's okay. You should go and do some sort of exercise. Go for a walk. It could be lighter if you're, you know, tired. But something in some form of movement, maybe yoga, stretching, whatever works for each person depending on how much pain they have. It really opens up the muscles and gives you relief.”

Other changes include,

• Manage stress: Practice stress-reduction techniques like meditation, yoga, or deep breathing.
• Prioritize sleep: Aim for 7-8 hours of quality sleep each night.
• Consider supplements: Consult with a healthcare professional about potential supplements, such as vitamin D and iron, to address specific deficiencies.

Non-healing mouth sores are often brushed off as minor issues, but when they persist for more than two weeks, they can signal something more serious.

Mouth ulcers are common and are often caused by stress, minor injuries, or nutritional deficiencies. Sores that do not heal may indicate underlying health concerns, particularly oral cancer.

"Early-stage oral cancers can present as painless ulcers or patches inside the mouth, making them easy to overlook. Conditions like Oral Cancer, Leukoplakia, or Lichen Planus may initially appear as harmless lesions but can progress if left unchecked," Dr. Mandeep Singh Malhotra, Director – Surgical Oncology at the CK Birla Hospital, Delhi, told HealthandMe.

Dr. Tejinder Kataria, Chairperson - Radiation Oncology, Medanta Hospital, Gurugram, added that mouth sores that don't go away after two to three weeks could be an early sign of oral cancer.

"These sores can be red or white and hurt or bleed easily. This is not the same as regular ulcers," he told HealthandMe.

The experts noted that non-healing sores can also be associated with systemic conditions such as

• vitamin deficiencies (especially B12 and iron),
• weakened immunity,
• chronic infections.

Oral cancer is a wide term for cancer that affects the inside of your mouth, and it typically presents itself as white patches or sores that bleed. It can occur on the:

• Lips.
• Gums.
• Tongue.
• Inner lining of the cheeks.
• Roof of the mouth.
• Floor of the mouth

It is estimated that about 60,000 new cases of oral cancer are reported annually in India, and five people die from the condition every hour. It is the most common cancer in Indian men and the third most common in women, with roughly 20 in 100,000 people affected.

Signs To Watch For

Oral cancer grows slowly, and the first signs usually don't hurt, so a lot of people don't notice them. However, it's important to look out for

• a change in voice,
• a lump in the mouth,
• trouble chewing
• A lip or mouth sore that won't heal.
• A white or reddish patch on the inside of the mouth.
• Loose teeth
• Mouth pain
• Ear pain
• Difficult or painful swallowing.

• Not brushing teeth,
• Tobacco use,
• Alcohol consumption,
• Ill-fitting dental appliances

How To Prevent

Early diagnosis plays a crucial role in effective treatment. If a mouth sore persists, grows, or is accompanied by pain, bleeding, or difficulty swallowing, it is important to consult a healthcare professional promptly. Paying attention to such small signs can make a significant difference in long-term health outcomes.

• Avoid smoking,
• drinking alcohol,
• Eat a lot of fruits and vegetables
• Keep your mouth clean.
• Going to the dentist regularly can help spot changes early.

Knee replacement surgery has witnessed remarkable advancements over the past few years. Traditionally, total knee replacement was performed as a uniform procedure ("one procedure fits all"), where the entire knee joint was replaced regardless of the extent or location of damage.

However, with the evolution of modern orthopedics, the focus has shifted towards precision and personalized treatment. In this direction, an A La Carte or Modular approach towards patients who need knee Replacement has emerged, which customizes or personalizes the surgery according to the patient’s specific condition.

Understanding The “à la carte” Concept

The term “à la carte” refers to selecting individual items from a menu. In knee replacement surgery, it means replacing only the damaged portion of the joint instead of the entire knee.

The knee is anatomically divided into three compartments:

• Medial compartment (inner side)
• Lateral compartment (outer side)
• Patellofemoral compartment (front portion involving the kneecap)

In many patients suffering from osteoarthritis, the disease affects only one or two of these compartments—most commonly the medial compartment. In such cases, replacing the entire knee may not be necessary. Modular implants allow surgeons to selectively treat the affected area while preserving healthy bone and ligaments.

The à la carte technique helps preserve the natural structure of the knee while effectively treating only the damaged portion, resulting in better and more natural functional outcomes for patients.

However, this approach is not suitable for all patients. It is generally not recommended in inflammatory conditions such as rheumatoid arthritis.

How It Differs From Total Knee Replacement

In Total Knee Replacement (TKR), all three compartments of the knee are replaced, making it an effective solution for advanced and widespread arthritis.

In contrast, Modular Knee Replacement offers a more targeted approach:

• Replacement of a single compartment (Partial Knee Replacement)
• Replacement of two compartments (e.g., medial + patellofemoral)

This selective treatment helps maintain the knee’s natural structure and function.

Advantages Of The Modular Approach

For carefully selected patients, this technique offers several important benefits:

• More natural knee function: Preservation of ligaments and bone provides a more natural feel.
• Faster recovery: Less invasive surgery leads to quicker rehabilitation.
• Reduced pain and blood loss: Minimal surgical trauma results in less discomfort.
• Improved mobility: Patients often achieve a better range of motion.
• Enhanced lifestyle comfort: Activities like sitting cross-legged or squatting may be easier and can be done unrestricted compared to total knee replacement.

Who Is the Ideal Candidate?

Not every patient is suitable for this procedure. Proper patient selection is one of the most critical factors in ensuring the success of this procedure. Ideal candidates typically include people:

• Having arthritis limited to one or two compartments
• Having stable knee ligaments
• Who do not have a severe deformity in the knee

Long-Term Outcomes

When performed in the right patient, modular knee replacement delivers excellent long-term outcomes (90 to 95 per cent survivorship for 15 years). Its success largely depends on accurate patient selection and flawless surgical expertise.

In some cases, if arthritis progresses in the remaining compartments over time, conversion to total knee replacement can still be done. However, this is relatively uncommon when proper indications are followed.

Role Of Robotic Technology

Robotic-assisted surgery has further enhanced the precision of this technique. It enables:

• Millimeter-level accuracy
• Precise implant positioning
• Restoration of patient-specific knee alignment

Conclusion

Ala Carte or Modular Knee Replacement represents a significant shift toward personalized orthopaedic care. Instead of a "one-size-fits-all " approach, surgeons can now tailor treatment based on the patient’s anatomy and disease pattern.

For many patients, this means less invasive surgery, faster recovery, improved function, and a more natural-feeling knee. Individuals experiencing persistent knee pain are advised to consult an orthopaedic specialist early to determine the most appropriate treatment option.

Beyond lung cancers, air pollution fine particulate matter (PM2.5) is increasing mortality for breast as well as liver cancers, according to a global study led by the Union for International Cancer Control (UICC), including researchers from the Indian Council of Medical Research (ICMR).

The important study showed that long-term exposure to PM2.5 increases the overall risk of developing cancer and the chances of dying from it compared with those living in cleaner environments.

For every 10 micrograms per cubic meter (µg/m³) increase in PM2.5 exposure, the overall risk of cancers increases by more than 11 per cent. At the same time, the risk of death also increases by more than 12 per cent for every 10 µg/m³ increase in PM2.5 exposure.

The researchers argued that while other common risk factors like tobacco and alcohol are being targeted with notable progress, air pollution is silently eroding the gains being made.

“We have made huge strides in reducing deaths from cancer, but polluted air is silently undermining that progress. It is a risk people cannot opt out of, and one that disproportionately affects women, children, and people living in poverty,” Cary Adams, CEO, UICC.

“The cancer community continues to make progress in addressing other major risk factors, including tobacco use, alcohol consumption, and viral, bacterial, or parasitic infections such as HPV and HBV that cause cervical and liver cancers. It is increasingly clear that air pollution must also be recognized as a major and preventable factor that increases the risk of developing cancer and of dying from the disease,” added Dr Elisabete Weiderpass, Director, IARC.

Risks of PM2.5: Beyond Lung Cancer

The study, based on data from 42 meta-analyses and systematic reviews published between 2019 and 2024, showed significantly strong associations for liver, colorectal, and breast cancers.

As per recent data from the International Agency for Research on Cancer (IARC), PM₂.₅ exposure contributes to 434,000 lung cancers per year, accounting for more than a quarter of preventable lung cancers in women and nearly one in six in men.

In addition to lung cancer risk, the study noted that the rising levels of PM2.5 are associated with

• a 32 per cent higher incidence of liver cancer
• an 18 per cent increase in the odds of developing colorectal cancer.

• a 12 per cent higher overall risk of dying from cancer,
• a 20 per cent higher risk of death from breast cancer,
• a 14 per cent from liver cancer,
• a 12 per cent from lung cancer.

Who Is At A Higher Risk

According to the researchers, people living in low- and middle-income countries bear the greatest overall burden. These countries frequently lack the resources to reduce pollution at source or to provide timely access to cancer prevention, diagnosis, and treatment.

The challenge is compounded by the projected rise in global cancer cases, expected to increase from 20 million in 2022 to 35 million by 2050. People at risk include:

• Women and children, particularly in settings where solid fuels are used for cooking and heating.
• Women exposed to household air pollution face a 69 per cent higher risk of lung cancer, alongside increased risks of cervical cancer.
• Outdoor workers and communities living near industrial facilities are also at heightened risk, with exposure often concentrated in economically deprived areas.

What Actions Are Required?

The researchers underscored that the evidence presented in the report is already sufficient to justify decisive action to reduce exposure to polluted air. They called upon policymakers to make required changes across energy, transport, industry, and urban planning to reduce the risk of cancer from air pollution.

The study urged the need for properly implementing effective interventions that are well-established. These include:

• Stronger emissions standards and enforcing the WHO air quality Standards
• A transition to clean energy and clean cooking
• Improved urban design by investing more in green infrastructure
• Expanded air-quality monitoring in High-Risk Areas
• Update cancer control plans.
