Karam Akoumeh is a patient at the Shifa Hospital in Gaza City.

His family said that his intestines were seriously damaged when he was shot while seeking food.

He is treated for abdominal wounds and has been increasingly malnourished because of a shortage of intravenous nutritional supplements, according to a doctor.

Karam's father said the lack of supplements and proper food for his condition, reduced his son’s weight.

“We need TPN (total parenteral nutrition), nutrients fed through the vein, for the injured Karam. I checked throughout all of Gaza’s hospitals for it (supplements), but I have not found any," said Atef Akoumeh.

The parents of Aya and Ahmad Sbeteh are also taking care of their children at Shifa where they are being treated for injuries.

15-year old Aya was wounded in an airstrike. Her recovery has been set back by weakness from lack of food that has significantly reduced her weight.

"Aya suffers from severe malnutrition due to shortages of nutritional supplements and possibly healthy food as well," said Dr. Mohammad Kuheil, Shifa Hospital's nutrition director.

He added that outside the hospital, the shortage of nutrients is equally dire.

"There are no protein sources, only plant-based protein from legumes. But if we talk about the meat, fish and chicken food group, then that is unavailable. The same for the dairy food group, it is unavailable. The same for the fruit group, it is unavailable," said Kuheil.

The overall death toll from malnutrition-related causes in Gaza is over 280, according to Gaza’s Health Ministry.

Israeli officials have pointed out that some of those said to have died from malnutrition had preexisting conditions. But experts say that is to be expected, as famine first preys on the most vulnerable.

The leading authority on global hunger crises said last Friday that parts of Gaza are in famine and is likely to spread across the territory without a ceasefire and a flood of humanitarian aid.

Israel rejected the famine announcement, calling it an "outright lie" and pointing to its recent efforts to allow in more food into the enclave.

It has accused Hamas of siphoning off aid — allegations disputed by the United Nations, which says Israeli restrictions and a breakdown of law and order make it extremely difficult to deliver food to the most vulnerable.
