Ace shuttler Saina Nehwal Wednesday pulled out of the Indian Open BWF World Tour Super 500 which begins here Tuesday, after failing to recover from an acute gastroenteritis problem.
She was forced to withdraw from Swiss Open last week and was admitted to hospital for treatment.
On Wednesday, Saina informed Badminton Association of India (BAI) about her decision to withdraw from the USD 350,000 tournament on medical grounds.
"She has not been well since the All England Championship. She sent the letter to withdraw citing stomach pain," a BAI official told PTI on condition of anonymity.
Last week, Saina, who had reached the quarter-finals of the All England Championship, had broken the news that she was advised to get admitted to get treated for her illness.
"So some sad news was really going through acute stomach pain from last Monday... managed to play few matches in All England with lot of pain ... decided to skip Swiss open and come back to India and find out the issue," she had written in her social media account.
"... and I found out it's acute gastroenteritis with mild pancreatitis and the doctors have recommended me to get admitted and hopefully I recover soon out of it."
Saina had won the India Open women's singles title in 2015. Olympic silver medallist and former champion P V Sindhu will now be India's only title contender in women's singles.
