Why You Shouldn’t Take Metformin for PCOS Management

Metformin is now the 4th most prescribed drug in the world for PCOS and diabetes, but one that has some horrific side effects and can be potentially life threatening.

But are we ever told about these at the clinic?! Nope, of course not. Not by the big pharma bizniss just wanting their pay check at the end of the month.

I was on metformin for over years, thinking it was going to be the miracle pill that would help me lose all my weight and make my life instantly better.

Unfortunately ladies I’m sorry to break it to you, there is no magic pill. There is no quick fix. 

I look back and remember how awful I felt taking not only metformin but the pill as well.

I got headaches so bad everyday I became addicted to ibuprofen.

My B12 dropped so low (as metformin depletes your body of this essential vitamin) that I could hardly stay awake, collapsed in my office several times and didn’t have enough energy to even carry my rucksack.

And what’s mad is that no one actually needs to be on metformin for PCOS or diabetes if they were just educated around balancing their blood sugars and controlling insulin through their diet?

Blows my mind still that we live in such a backwards world, but that’s why I won’t stop trying to educate and help Women to realise what actually works and what we’ve just been conditioned to believe. 

Potential Side Effects and Risks

Gastrointestinal Issues:

One of the most common side effects of Metformin is gastrointestinal discomfort. Many women experience nausea, diarrhoea, and abdominal pain when they start taking this medication. 

These symptoms can significantly affect daily life and may discourage consistent use. 

Honestly ladies, if you have IBS or suffer with bowel issues anyway, this is only going to make it hellllla worse. 

Risk of Lactic Acidosis:

Lactic acidosis is a rare but serious side effect of Metformin. This condition occurs when lactate builds up in the bloodstream, leading to a decrease in blood pH. 

It can be life-threatening if not promptly treated. Individuals with kidney problems or those taking high doses of Metformin are at a higher risk. Although lactic acidosis is rare, its potential severity warrants careful consideration before starting Metformin.

Long-term Effects:

The long-term effects of Metformin generally increase your risk of developing diseases such as cancer and CVD drastically. Additionally, there are concerns about the medication’s effects on bone health. 

As with any long-term medication, the potential risks should be weighed against the benefits.

I can absolutely promise you, you do not need metformin to heal your PCOS.

Everything can be done with a few changes to your diet and lifestyle, just like I’ve done and helped hundreds of other women do the same.

Insufficient Evidence for Comprehensive Management

Research Limitations:

While Metformin is widely used for PCOS, there are gaps in the research regarding its long-term efficacy and safety.

Did you know it was actually recalled in America for its high link with cancer?

Many studies focus on short-term outcomes, leaving uncertainties about the medication’s benefits and risks over an extended period.

This is why we can never trust many ‘studies’ out there as the variables are all over the place and they are run on small groups of humans.

More comprehensive research is needed to fully understand if it actually does help PCOS (I can confirm it does not) but I am not trying to be bias here. 

Misleading Benefits:

Metformin is often touted as a cure-all for PCOS, but it is essential to recognise its limitations.

It will not help you lose a stone overnight.
It will not make your acne disappear.

It will not have your energy soaring that you’re jumping out of bed.

Trust me –  I wish it would be just as much as you, but once you swallow this pill and realise you’ve gotta do a bit of the hard work – your journey can begin. 

Alternatives to Metformin

Lifestyle Modifications:

Diet and exercise are fundamental components of PCOS management. A balanced PCOS diet rich in whole foods, lean proteins, and healthy fats can help regulate blood sugar levels and reduce symptoms. 

Regular physical activity improves insulin sensitivity, supports weight management, and enhances overall well-being.

Herbal and Natural Remedies:

I am a big fan of anything natural and herbal! The more you can put into your life the better to be honest.

Supplements such as inositol, cinnamon, and spearmint tea have shown promise in improving insulin sensitivity and reducing androgen levels.

As I don’t want you wasting anymore money, when clients work with me 1 to 1 I can identify quickly where their imbalances and deficiencies are, and where they might need to supplement.
