Parasitic infection (Entamoeba histolytica) causing dysentery and liver abscesses
VA doesn't add ratings together. It combines them using the table in 38 CFR § 4.25, so two ratings usually total less than their sum.
When the disease is active, medical records showing a confirmed amebiasis diagnosis, lab results, imaging, hospital records, or treatment notes all help establish the 100% level. Once the active phase ends, evidence of any lasting damage becomes the focus. Records documenting ongoing organ involvement — such as liver function tests, imaging showing abscess or scarring, colonoscopy findings, or specialist evaluations — help establish residual conditions. Your own statements and those of people who know you, describing how symptoms affect your ability to work, eat, or carry out daily activities, can support the severity of any residual disability. The residual condition is then rated under whichever body system it falls into, so evidence should speak directly to the criteria for that condition.
