Patients who have brought themselves to the brink of malnutrition by exaggerated dieting, laxatives etc, often have an abnormally low blood pressure. In these cases the blood pressure rises to normal values at the beginning of treatment and then very gradually drops, as it always does in patients with a normal blood pressure. Normal values are always regained a few days after the treatment is over. Of this lowering of the blood pressure during treatment the patients are not aware. When the blood pressure is abnormally high, and provided there are no detectable renal lesions, the pressure drops, as it usually does in pregnancy. The drop is often very rapid, so rapid in fact that it sometimes is advisable to slow down the process with pressure sustaining medication until the circulation has had a few days time to adjust itself to the new situation. On the other hand, among the thousands of cases treated, we have never seen any untoward incident which could be attributed to the rather sudden drop in high blood pressure.
When a woman suffering from high blood pressure becomes pregnant her blood pressure very soon drops, but after her confinement it may gradually rise back to its former level. Similarly, a high blood pressure present before HCG treatment tends to rise again after the treatment is over, though this is not always the case. But the former high levels are rarely reached, and we have gathered the impression that such relapses respond better to orthodox drugs such as Reserpine than before treatment.
