what is a low basal body temperature hypothyroid?

Barnes found that a normal resting body temp should be between 97.8-98.2 degrees Fahrenheit. If it is consistently lower, then there is a trend toward a hypothyroid (decreased function) pattern. If consistently above 98.2, then this indicates a trend for more of a hyperthyroid (increased function) presentation.

Cold intolerance is a well known symptom of hypothyroidism. Hypothyroidism occurs when the thyroid gland does not produce enough thyroid hormones. These hormones help regulate metabolism and temperature. When the thyroid is not producing enough thyroid hormones, the body's processes tend to slow down.

People with hypothyroidism may also have a slower heart rate, or bradycardia. Low thyroid levels can affect the heart in other ways too. These effects may include: changes in blood pressure.

Hyperthyroidism (too much thyroid hormone) may cause palpitations, shortness of breath, and lightheadedness. Hypothyroidism (too little thyroid hormone) may cause low blood pressure and a decreased heart rate leading to lightheadedness, weakness, lethargy, and chills.

Low TSH levels indicate hyperthyroidism. If the thyroid gland is secreting levels of hormones that are too high, the pituitary gland produces less TSH.

Usually they receive a T4 dose large enough to suppress their blood level of thyroid stimulating hormone (TSH) below the normal TSH range. This is called TSH suppression.

Low TSH levels can mean your thyroid is making too much of the hormones, a condition called hyperthyroidism. A TSH test does not explain why TSH levels are too high or too low.

It also plays an important role in regulating your weight, body temperature, muscle strength, and even your mood. TSH is made in a gland in the brain called the pituitary. When thyroid levels in your body are low, the pituitary gland makes more TSH. When thyroid levels are high, the pituitary gland makes less TSH.

Brief Temperature Drop as a Pregnancy Indication An implantation dip is a one-day drop in your basal body temperature (BBT) that occurs during the luteal phase, about seven to 10 days after ovulation. This drop is seen on pregnancy charts more often than non-pregnancy charts.

Hypothyroidism causes symptoms like slowed metabolism, tiredness, and weight gain. Having an underactive thyroid can decrease or slow down your bodily functions. With hyperthyroidism, you may find yourself with more energy, as opposed to less. You may experience weight loss as opposed to weight gain.

Basal body temperature typically drops about one to two days before the onset of the period – this temperature shift signifies that the corpus luteum is disintegrating and progesterone is no longer being produced. In response, the endometrial lining loosens and begins to shed – this is menstruation.

“Because thyroid hormones are involved in so many bodily processes, when they are low, you can have both daytime and nighttime symptoms, including fatigue during the day and poor sleep at night.” Besides causing daytime fatigue by slowing metabolism, hypothyroidism increases the risk for some sleep disorders.

BBT is slightly lower in the follicular phase (the first half of the menstrual cycle), and rises after ovulation and stays raised throughout the luteal phase (the second half of the menstrual cycle) (2,3). This rise in temperature happens in response to progesterone, which is released after ovulation occurs.

Right before ovulation, basal body temperature usually drops, with a sharp increase right after ovulation. ... Most often BBT falls between 97.52–98.24 °F (36.4–36.8 °C) because of low progesterone concentration.
