Salt water (1 piece)

Use plain water or unsweetened electrolyte water without sugar, dextrose, maltodextrin, or flavored syrup; salt itself does not usually raise glucose directly.

Check the salt-water product label and serving size, since packaged electrolyte mixes or “hydration” drinks may contain carbohydrates.

Avoid drinking a concentrated salt solution, which can cause thirst, nausea, and fluid-balance problems; use only the amount advised by a clinician if you need sodium replacement.

If you need to take salt water with food, pair it with a small protein- and fiber-rich option such as plain Greek yogurt, eggs, or a small handful of nuts.

Measure glucose again after washing and drying your hands and using a new test strip, since residue or meter variation can create a small apparent rise.

If rises recur despite plain salt water, note timing, stress, exercise, caffeine, illness, and medications, and discuss persistent or unexpected changes with a healthcare professional.
