Smoking May Quietly Undermine PMOS Management, Doctors Warn

Women with Polyendocrine Metabolic Ovarian Syndrome, or PMOS, are often told the same things: eat better, move more, sleep properly, manage stress. Many spend years working through that list. According to Dr Akshat Chadha, who offered his views to TOI Health, one habit rarely makes it into the conversation even though it can undo almost every other effort. That habit is smoking.

The warnings attached to cigarettes usually concern the lungs, the heart and cancer. Chadha's argument is about a quieter kind of harm. He points to the recent shift in terminology from PCOS to PMOS, which he describes as more than a change of name. It acknowledged that the condition reaches well beyond the ovaries, into hormones, metabolism, reproductive health and emotional well-being. Smoking, he says, touches nearly all of those areas.

Start with insulin resistance, which sits at the centre of PMOS for many women. The body struggles to use insulin properly, which can mean higher blood sugar, weight gain and a greater eventual risk of Type 2 diabetes. Research has shown that nicotine can interfere with insulin signalling and make blood sugar harder to regulate. The US National Institute of Diabetes and Digestive and Kidney Diseases notes that smoking raises the risk of Type 2 diabetes and can worsen metabolic health. For a woman with PMOS, that may intensify a problem already present.

Then there are the visible symptoms: stubborn acne, unwanted facial hair, thinning hair on the scalp, all linked to excess androgens. Chadha says smoking can amplify those hormones, because cigarettes influence how the body produces and metabolises them. Symptoms a woman is already working to control can flare or resist treatment. Several studies have suggested smoking may alter hormone levels and the processing of reproductive hormones. These signs are not merely cosmetic, the article notes; they can affect confidence, social interactions and mental health.

Menstrual cycles are affected too. Chadha explains that women who smoke are more likely to have longer gaps between periods, unpredictable cycles and more severe premenstrual symptoms. The US Office on Women's Health links smoking to menstrual problems and fertility concerns. Since PMOS already makes cycles irregular, smoking can make them harder still to predict. Some women who quit report better regularity over time, though recovery varies with age, weight and overall health.

Fertility carries a double burden. PMOS often affects ovulation and egg quality, and Chadha says smoking independently reduces ovarian reserve and makes conception harder, through mechanisms separate from the syndrome. Doctors often advise women planning a pregnancy to quit as early as possible, because the body begins to benefit soon after. Removing smoking will not resolve PMOS, but it can remove one significant barrier for couples already dealing with anxiety, guilt and frustration.

The risks extend to the heart and mind. Women with PMOS already face higher risks of metabolic problems and cardiovascular disease, and smoking compounds them. Many are also prescribed oral contraceptive pills to manage symptoms; smoking while taking them can raise the risk of blood clots, stroke and other serious cardiovascular complications. Anxiety and depression are more common in women with PMOS, and nicotine dependence can add its own cycle of stress and mood changes.

Quitting, the article stresses, does not cure PMOS, and there is no evidence it can fully reverse the condition. But over time it may improve insulin sensitivity, lower cardiovascular risk, reduce nicotine-related hormone disruption, improve fertility outcomes and make diet and exercise changes more effective. Chadha frames it without judgment: one habit may be working against everything else a woman is doing right, and changing it could shift the trajectory more than she expects. The piece rests on one expert's commentary, so the next thing to watch is formal clinical guidance on smoking cessation within PMOS care.
