High heart rate
Sit quietly for ten minutes and check pulse.
Take a full teaspoon of unrefined sea salt in a glass of water (8-12 ounces). In one hour, recheck pulse. If it lowers considerable, the high pulse is from low sodium.
For those on T3 medication, a second test would be to take a dose of T3 and again wait an hour and retest heart rate. If it lowers considerably, it is from low T3.
For those taking HC, take an extra 2.5 mg dose of HC and wait an hour and retest. If it lowers considerably, it is from low cortisol.
Low stomach acid
This test is to help determine if your stomach is producing sufficient hydrochloric acid which is necessary for good digestion. A reduction in the production of stomach acid is common as people age but it is also a common symptom of low thyroid.
Before eating in the morning, make a solution of one quarter of a teaspoon of baking soda in eight ounces of water and drink it. If you are producing sufficient stomach acid, you would expect to burp in two to three minutes. If drinking the solution does not cause a burp within five minutes, there is a good chance you have low stomach acid.
Low aldosterone
Pupil Test
Go into a dark room or closet with a flashlight and mirror. After a few minutes with eyes open in the darkness, shine the light into your eyes from the side. Observe the pupils. Pupils will get small and should stay small and steady. If after a while they flutter or get larger again, it is an indication of low aldosterone.
Orthostatic hypotension
Orthostatic hypotension, or blood pressure which drops upon standing, is another indication of low aldosterone. Rest for five minutes lying down, then take a blood pressure reading. Stand up and immediately take the blood pressure again. The standing readings of both systolic and diastolic numbers should rise as the body elevates blood pressure to push blood to the brain. Failure to elevate indicates low aldosterone.
