3.0 out of 5 stars Not sure if it's me or the thermometer, 31 Oct 2013
Verified Purchase(What is this?)
This review is from: Geratherm Basal Digital, Digital cycle thermometer for determination of the time of ovulation. (Personal Care)
This is the second thermometer I have tried (though the first was not a basal thermometer) and I still have the same issue. My temperature seems to be different every time I take it and does not just rise, but also falls and the difference can be quite big. I now just very confused.

I'd say you have both thyroid and adrenal issues. Below are some home self-tests. If any of them are relevant, I recommend:

1. the book "Stop the Thyroid Madness", a fantastic self-help manual for both thyroid and adrenal problems
2. see Dr Durrant-Peatfield (private, clinic near Gatwick), who saved my life.


The basal (at rest) temperature test is THE gold standard for low thyroid problems and - with your symptoms - means more than any lab test (although most doctors won't agree). It will pick up conditions that current lab tests don't, such as thyroid resistance. A basal temperature is taken when you wake up in the morning, BEFORE you get out of bed (NOT after you have seen to the baby or made a tea or gone to the toilet). Socks, heated blankets or layers of clothes/blankets will skew results.

In women of childbearing age, body temperature varies with the monthly cycle, creating errors that can be avoided if temps are checked before day 15 of your cycle, with the first day being the day you start your bleeding time. Men and non-menstruating women can take their temps on any day. Mercury thermometers are the most accurate but no longer sold in the EU or USA. Do NOT use ear thermometers and avoid digital ones, which can be off by up to .5C (1F) - EXCEPT the Geratherm Basal Digital thermometer (about 20 from but you MUST keep it in for 2 minutes after the 4 beeps, you will see that it continues to go up (if you check quickly about every 30 seconds).

Place the thermometer snugly under your armpit. Leave a mercury/liquid one there for 10 minutes by the clock. Write down the reading: normal temperature is: 36.7C - 36.8C -(98F - 98.2F) (Armpit is more reliable as so many of us have chronic low-grade upper respiratory inflammations - sinus, ear, nose or throat - so mouth temperature readings can be misleading.)

Ideally, check both temp and pulse three times a week. On those three days a week, always do it twice: the first time BEFORE you get out of bed in the morning and the second time about 12 hours later. Write them down, together with the date. A "finger pulse oximeter" makes this easier and can be purchased from as little as 20 from ebay and amazon.

If your basal temperature is below 36.6C (97.9F), hypothyroidism (low thyroid) should be considered if symptoms are present. If your temperature is above 37.4C (99.2F), hyperthyroidism is possible if symptoms are present and if there is no other illness then, to cause a fever. This test is a guide only: some temperatures could be due to infection, virus, etc.

The following are self-tests for adrenal insufficiency:

Let someone shine a bright light your way. Do you find yourself very sensitive and uncomfortable with the bright light (similarly with bright summer sunshine)? That could be a sign of adrenal fatigue. This can also be true if you have searing headaches along with the sensitivity. You need adrenal support.

This is called the Pupil test and primarily tests your levels of aldosterone, another adrenal hormone. You need to be in a darkened room with a mirror and a flashlight/ torch/ penlight. Do this later in the day as results are more reliable then. From the side (not the front), shine a bright light towards your pupils and hold it for about a minute. Carefully observe the pupil. With healthy adrenals (and specifically, healthy levels of aldosterone), your pupils will constrict, and will stay small the entire time you shine the light from the side. In adrenal fatigue, the pupil will get small, but within 30 seconds, it will soon enlarge again or obviously flutter in its attempt to stay constricted. You need adrenal support.

Why? Because adrenal insufficiency can also result in low aldosterone, which causes a lack of proper amounts of sodium and an abundance of potassium. This imbalance causes the sphincter muscles of your eye (and often other sphincters too) to be weak and to dilate in response to light. (Note: there are over 50 sphincters in the body and, for instance, stress incontinence due to adrenal fatigue is difficult to fix just with pelvic floor exercises.)

Take and compare two blood pressure readings-one sitting (rested and quiet) and the other while standing. Rest for ten minutes (sitting, not lying down) before taking the first reading. Stand up and immediately take the blood pressure again. If the blood pressure is lower after standing, suspect adrenal gland problems and more specifically, an aldosterone issue-another adrenal hormone. The degree to which the blood pressure drops while standing is often proportionate to the degree of hypoadrenalism. (Normal adrenal function will raise your BP on the standing reading in order to push blood to the brain.) It can be wise to do this test both morning and evening, since it can be normal one time but not another. (Home blood pressure monitors are cheap from Amazon & Ebay.)

Take your temp 3 times a day, starting three hours after you wake up, and every three hours after that, to equal three temps. (If you have eaten or exercised right before it's time to take your temp, wait 20 more minutes.) Then average them for that day. Do this for AT LEAST 5 days. If your averaged temp is fluctuating from day to day more than .1C to .2C (.2F to .3F), you need adrenal support. Your daily average temps should lean towards the .1C / .2F when on enough adrenal support for your needs.

If your temps are fluctuating but overall low, you need both adrenal and thyroid support.
If your temps are fluctuating but averaging 98.6, you just need adrenal support.
If it is steady but low, you need thyroid support and adrenals are likely fine.
(mercury thermometers are the most accurate but very difficult to buy nowadays, next best are liquid thermometers, then digital thermometers. Do NOT use ear thermometers.)

This is the easiest home test for adrenal deficiency, from Wilson's excellent 2001 book (still a classic) called "Adrenal Fatigue": all you need for this test is a ball point pen. Drag the dull end of a pen across your abdomen for about six inches (my guess would be about 2 fingers' width above or below your belly button) but don't press overly hard or scratch the skin. If your adrenals are functioning normally or are only mildly affected, the mark will turn from white to red within about 10 seconds. If your adrenals are fatigued, however, the line will widen and stay white for about 2 minutes. This test isn't terribly accurate as it only shows up on about 40 per cent of people with low adrenal function. It generally stays white only if the adrenal fatigue is fairly severe. If it does show, YOU NEED ADRENAL SUPPORT!

Note: a good adrenal supplement is Nutricology Pregnenolone (also available from Amazon) but you should cut the tablet into smaller pieces, starting at bout 10mg and working SLOWLY up to about 50mg FIRST THING IN THE MORNING.
