New mum Jenny Mollen opens up about potential Graves diagnosis with shocking weight loss snap

New mum Jenny Mollen has opened up about her potential Graves diagnosis by sharing a shocking weight loss picture.

The actress and author, who welcomed her second child with husband Jason Biggs in October last year, took to Instagram to share how much weight she has lost in the past few months, which is likely due to the condition.

Alongside the mirror selfie where her gaunt torso can be seen, she explained that she had noticed she was getting thin but didn't think there was something wrong until she found a 'bulge' in her neck.

While she's still waiting for the test results, her doctor believes she has an overactive thyroid - also known as hyperthyroidism - which could be caused by Graves, an autoimmune condition that means the immune system mistakenly attacks the body and by attacking the thyroid, it causes it to become overactive.

She wrote: 'Not anorexia, it’s a thyroid issue. I don’t know what it says about me that I got this thin and didn't think there was anything wrong. Last Friday, I had a bulge in my neck that finally got me to the doctor. I'm STILL waiting on blood work but my doc thinks it's Graves.'

In the same post, the 38-year-old then goes on to urge mums to look out for the symptoms like weight loss and hair loss, as it could mean they're suffering from the same condition.

'If you just had a baby and have lost an inordinate amount of weight, feel like you are on cocaine, are suddenly heat intolerant, can't stop losing hair, and think your husband is being a dick it might just be your thyroid!! Get checked ASAP #thyroid #6monthspostpartum', she explained.

Just a few days ago, the mum had done a similar post on Instagram where she explained that she had finally taken tests to find out why she was rapidly losing weight.

'Many of you have written and asked me about my rapid weight loss. Weight loss that to be honest, I couldn’t really explain until now. This morning I woke up w a giant bulge in my neck the size of a golf ball. I had blood work and an ultrasound and will be waiting for the results over the weekend', she said.

'Though I am not certain, I have good reason to believe it is some sort of hyperthyroidism. Apparently this is common in women AFTER PREGNANCY.'
