Sixty-five people remain in hospitals after the bombings in London, many having had operations after losing limbs, and suffering burns.
More than 700 people were injured in the London blasts
More than 700 people were hurt and at least 50 died in Thursday's attacks, with many people still missing.
Hospitals called in extra staff and cancelled non-urgent surgery to deal with the injured, but have now returned to normal working conditions.
People worried about relatives or friends should call 0870 1566 344.
On Saturday, Professor Jim Ryan, a senior A&E consultant at University College Hospital - which is still treating 15 people - said: "Most of the operations are on limbs. You have penetrating wounds, indented stone, debris, glass or metal.
"There is also head injury management, and lung inhalation and injuries to the chest."
On Sunday, the Royal London Hospital, near Liverpool Street Station, said it was still treating 17 patients, seven who were in intensive care.
Chelsea and Westminster Hospital has four blast victims being treated in their specialist burns unit, after two were released on Saturday night.
The Royal Free Hospital, in north London, said it was still treating seven people, all in a stable condition, with one expected to be discharged later on Sunday.
And St Mary's Hospital, in Paddington, is treating five people. All were in a stable condition, with two said to be critical.
Thirteen people are still at Guy's and St Thomas's, near Waterloo, one in a critical condition but stable.
Five underwent surgery on Saturday.
And Great Ormond Street Hospital for Children, which set up makeshift facilities under its major incident plan as it does not have an A&E department, still has two casualties.
A spokesman said they were "doing reasonably well" and may be discharged within the next 24 hours.
Charing Cross Hospital has two casualties, both of whom were transferred from St Mary's and are described as being in a stable condition.
Casualties have received visits from Health Secretary Patricia Hewitt, The Queen and Prince Charles.
Speaking at the Royal Free Hospital on Saturday, Ms Hewitt praised the NHS response, saying hospitals were "almost immediately ready and could have coped with far more people had they needed to".
