“Madam (Khaleda) was taken to the hospital as she fell ill suddenly,” said BNP’s health affairs secretary Dr Rafiqul Islam.
Party sources said Khaleda’s personal doctors, party secretary general Mirza Fakhrul Islam Alamgir and some senior leaders went to her residence at midnight after hearing the news of her illness.
Later, she was taken to the hospital as per the suggestion of the medical board formed earlier for her treatment.
The BNP chief’s younger brother Shamim Eskandar drove her to the Hospital in a private car.
She last went to the same hospital on April 29 last and received treatment there for five days.
The BNP chief received treatment at the hospital seven times since she was infected with Coronavirus in April, 2021.
Khaleda, a 78-year-old former prime minister, has been suffering from various ailments, including liver cirrhosis, arthritis, diabetes, kidney, lung, heart and eye problems.
Since her conditional release in 2020, the BNP chief has been receiving treatment at the hospital under a medical board headed by cardiologist Prof Shahabuddin Talukder.
On June 10 last year, the BNP chief suffered a heart attack due to a 95 percent block in her left artery and a stent was placed there by removing the blockage at the same hospital the following day.
Doctors also found two more blocks in her blood vessels, but they could not remove those due to her health complications.
Khaleda was sent to the Old Dhaka Central Jail as a lower court sentenced her to five years’ imprisonment in the Zia Orphanage Trust corruption case on February 8, 2018. Later, she was found guilty in another corruption case the same year.
Amid the coronavirus outbreak, the government temporarily freed Khaleda Zia from jail through an executive order suspending her sentence on March 25, 2020, with conditions that she will stay in her Gulshan house and will not leave the country.
