A diuretic is any drug that elevates the rate of urination and thus provides a means of forced diuresis. There are several categories of diuretics. All diuretics increase the excretion of water from bodies, although each class of diuretic does so in a distinct way. Some diuretics are contraindicated for MP patients.
Thiazide diuretics are too hard on the kidneys and liver, organs in which patients with Th1 disease may have both diagnosed and subclinical problems. Thiazide drugs are contraindicated for patients on the Marshall Protocol, and especially for those with kidney disease.
Patients can read the precautions about HCT on the RxList: the Internet Drug Index.
These diuretics are contraindicated because they are potassium-sparing and might result in hyperkalemia.
Lasix (furosemide) however, does not cause potassium-retention and is compatible with the Marshall Protocol. Anyone on Lasix with cardiorespiratory symptoms exacerbation should be evaluated by their doctor for congesitve heart failure to see if their cardiac medications need to be adjusted.
