A high ratio of estrogen to progesterone can lead to overgrowth of the lining of the uterus. Then uncoordinated shedding of the lining can lead to ongoing vaginal bleeding.
Estrogen is responsible for the growth of the endometrium, or uterine lining. The progesterone added at ovulation changes its growth pattern. This is why unopposed estrogen, as with poorly-planned estrogen replacement therapy or in the case of metabolic diseases like polycystic ovarian syndrome, can lead to overgrowth ("hyperplasia") of the uterine lining.
Female sex hormones, such as estrogen and progesterone, have been found to have an impact on heart rate and palpitations. Estrogen, in particular, has been observed to increase heart rate, while progesterone has a more variable effect. Estrogen, which is primarily produced by the ovaries, has been shown to have a direct effect on the cardiovascular system. It can stimulate the release of nitric oxide, a substance that relaxes blood vessel walls, leading to vasodilation. This dilation of blood vessels can result in an increase in heart rate. Additionally, estrogen has been found to affect the autonomic nervous system, which controls heart rate, by increasing sympathetic activity and decreasing parasympathetic activity. Progesterone, on the other hand, has a more complex influence on heart rate. It has been found to have both stimulatory and inhibitory effects, depending on the concentration and the phase of the menstrual cycle. In the early stages of the menstrual cycle, when progesterone levels are low, it can have a stimulatory effect on heart rate. However, during the luteal phase, when progesterone levels are high, it may have an inhibitory effect on heart rate. Palpitations, which are characterized by a rapid or irregular heartbeat, can also be influenced by female sex hormones. Estrogen has been associated with an increased risk of palpitations, particularly during times of hormonal fluctuations such as pregnancy, menopause, or during the menstrual cycle. This may be due to the effects of estrogen on the autonomic nervous system, which can lead to increased sympathetic activity and subsequent palpitations. In summary, female sex hormones, specifically estrogen and progesterone, have a significant impact on heart rate and palpitations. Estrogen tends to increase heart rate, while progesterone has a more variable effect. Understanding these hormonal influences is important in managing cardiovascular health, particularly in women, and may help in the development of targeted interventions for heart-related conditions.
Lead poisoning will occur if high levels of lead occur in the blood.
While high lead levels are linked to mental retardation and central nervous system damage in infants and children, they have not been specifically linked to autism.
yes
Arteriosclerosis.
sick because lead is a toxic subtance
Sort of. You can get lead poisoning or high lead levels if you shoot regularly at an indoor range.
Yes, it has high levels of lead and can cause symptoms of lead poisioning.
A lot of foods that are high in protein are also high in purines thatcause a raising in uric acid in the blood. this can lead to gout.
