BNP Chairperson Khaleda Zia was taken to Evercare Hospital in the capital on Saturday evening for health check-ups.
She arrived at the hospital from her Gulshan residence around 6:45pm, said her media wing member Sayrul Kabir Khan.
He said the BNP chairperson will undergo several tests at the hospital as per the advice of her medical board.
Khaleda, a 77-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.
She visited the same hospital for health check-ups on February 27 last. Khaleda received treatment at the hospital six times since she was infected with Coronavirus in April, 2021.
In November 2021, Khaleda Zia was diagnosed with liver cirrhosis.
On June 10 last, 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’ imprison-ment 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 ex-ecutive order suspending her sentence on March 25, 2020, with conditions that she will stay in her Gul-shan house and will not leave the country.
