Leukemia and high blood pressure: cutting salt
Steroids, ciclosporin, tacrolimus and some TKIs can raise blood pressure, which is harder if you already have hypertension. Eating well helps control it. This section covers the main steps.

01Short answer
02Simple explanation
Under 5 g of salt.
Flavour with herbs.
Measure at home.
Do not stop medicines.
03Scientific explanation
WHO: reducing salt intake lowers blood pressure and the risk of cardiovascular disease.
ESPEN: enough energy and protein matter for preventing weight and muscle loss in people with cancer, and nutritional status should be assessed regularly.
NCI: practical eating tips exist for treatment side effects such as nausea, taste changes and mouth sores.
04What happens in the body?
Potassium
Potassium is good for blood pressure but may be limited with kidney disease; see “Leukemia and kidney disease: fluid, salt and potassium”.

Salt substitutes
They contain potassium; ask your team.

Dietitian
If you are losing weight, have no appetite or need a special diet, ask to see the hospital dietitian.
Food safety
Food-safety rules for neutropenia (see “Handwashing: the simplest protection” and “Eggs and dairy: safe choices”) apply at every stage.
05Nutrition: four steps
Assess, swap the risky, cook safely, eat regularly.
