London:Dannii Minogue has revealed she suffered from thyroid problem which made her too weak.
The 39-year-old star, who has a 15-month-old Ethan with partner Kris Smith is still recovering, reports femalefirst.co.uk.
"I was getting thinner and thinner and stressing because I didn`t know what it was. Normally you put on weight if you have an under-active thyroid but there is a percentage of people that have it reversed. It got very hard to concentrate, you can`t sleep and I got very weak," she said.
"I was finding it hard to pick Ethan up and I was thinking, `I`m a new mum, I know I`m tired but surely it can`t be this hard?` When you`ve just had a baby you think it must be normal tiredness but it got to the point where I thought, `This can`t be normal", she added.
