One of the criteria for admission into the OTP program is oedema +, ++. Is SAM the only cause of bilateral oedema in children? If presence of oedema alone is a criteria for admission, how can we be sure that the oedema is not the result of other causes other than SAM?

Other causes of oedema are CCF(congestive cardiac failure) and AGN (acute glomerulonephritis).

the SAM oedema is characterized: 1) oedema should be bilateral. 2) oedema will start from feet. 3) pitting sign will be positive
