Helminthic therapy and cardiometabolic conditions
Metabolic disorders are disorders that negatively alter the body's processing and distribution of proteins, fats and carbohydrates.
Cardiovascular diseases involve the heart and blood vessels.

Blood pressure[edit | edit source]
Not everyone using helminthic therapy will experience a change in blood pressure.
However, helminthic therapy can reduce blood pressure in some cases, especially if it had previously been elevated.
The reduction in blood pressure seen by some users of helminthic therapy may be a result of the worms correcting an autoimmune condition.
Lowered blood pressure may not be advantageous for everyone, especially those on the fatigue spectrum, in which case starting helminthic therapy with too high a dose might result in blood pressure dropping too far, causing dizziness or even a brief loss of consciousness.

Helminth infections improve lipid profiles and may lower blood pressure.
Several studies show a link between dysbiosis and hypertension. Helminths reshape microbiota and could therefore have an impact on these cases, which would be interesting to investigate.

Cardiovascular disease[edit | edit source]
Also see Atherosclerosis, above.
Nearly half of all adult Americans have cardiovascular disease. [9]
Immunotherapies that treat inflammatory conditions might have a role in the reduction of cardiovascular disease risks, [10] and anti-inflammatory medication allows patients with a history of heart attacks to enjoy a significantly lower incidence of recurrent cardiovascular events, [11] but these drugs may only be necessary because of the helminth deficiency that is widespread throughout the developed world in the twenty first century.

- This rigorous, comprehensive systematic review has revealed that individuals who are hosting helminths enjoy less dyslipidemia (unhealthy levels of fats in the blood), less metabolic syndrome, less diabetes, and less atherosclerotic cardiovascular disease.
- Its authors warn that, if individuals who are at moderate or high risk for cardiometabolic disease are deprived of their helminths as a result of de-worming campaigns, they may require an increase in preventive medical care to compensate for the loss of beneficial helminth-derived immune modulation.

… multiple lines of evidence support the notion that there is also an inverse relationship between helminthic infections and atherosclerosis and its related diseases. It is hereby hypothesized that worms are ‘protective’ against heart disease.
