In 2022, the number of cases of severe preeclampsia at the South Kalimantan Provincial Health Service will be 818, while at the Ulin Regional Hospital, Banjarmasin, 78 cases will be recorded. The impact of preeclampsia is not only hypertension which causes dizziness/headaches, it also causes nausea, vomiting, epigastric pain, and even affects kidney, heart and liver function which is a physical health problem.Objective: This study aims to determine the quality of physical health of postpartum mothers with severe preeclampsiaMethods: This research is a quantitative descriptive study using a retrospective study. Sampling used a total sampling method of 78 postpartum mothers with severe preeclampsia in 2022Results: The results of research on the blood pressure of postpartum mothers with severe preeclampsia from day 1 to day 3 found hypertension in 25.7% of postpartum mothers, complaints of headaches, epigastric pain, nausea, vomiting, shortness of breath, and even fever. The results of laboratory examinations on the third day showed that 3 people (4%) had thrombocytopenia, 2 people (3%) had thrombocytosis, 19 people (24%) had increased SGOT values, 6 people (8%) had increased SGPT values, 31 people (40%) increased LDH values above normal, 8 people (10%) increased creatinine values and 11 people (14%) increased urea valuesConclusion: This research proves that the physical health of postpartum mothers with severe preeclampsia is mostly still healthy, but there are still some postpartum mothers whose physical health is not optimal (40%) due to hypertension, physical problems/complaints of headaches, epigastric pain, nausea and vomiting, shortness of breath, fever and increased function of the liver, heart and kidneys based on laboratory results on the third day of the postpartum periodSuggestion: When you feel any discomfort, immediately report it to the health worker/midwife so that care related to the clinical condition is more targeted and specific.
