Innan mens blir min kropp mer resistent mot insulin värkar det som. Aldrig har någon berettat att det finns spesifika kopplingar med hormonerna som produseras under ägglösning versus när man har mens och direkt efter, så jag vill tipsa andra som känner att dem registrerar det här. Jag vet nu jag kan med säkerhet höja min dos innan mens, och att det inte är någon slumpmessig höjning. Länk:

(Jag har fått bekräftat av läkare etc att det påvärkar men kan dem inte vara mer spesifika? ?? Det är så intressant med kopplingen estrogen och insulinsensitivitet. Man kan jo undra om låga estrogen nivå kan leda till diabetes.Jag har typ 1.)

Från texten:

Researchers haven't established a clear connection between menstrual cycles and blood sugar control, but some studies have shown a link. Here's a look at how and why your periods and your blood sugar may interact, whether you have type 1 or type 2 diabetes.

Your ovaries produce the hormones estrogen and progesterone, which regulate your menstrual, or reproductive, cycle. As the hormone levels fluctuate during the cycle, so can your blood sugar.

Your menstrual cycle has two phases: follicular and luteal. The follicular phase begins on the first day of bleeding. During the early part of this phase, estrogen and progesterone levels are low. The ovaries then begin gradually increasing production of estrogen as a result of the developing egg cell. At midcycle, around day 14, one of your ovaries releases an egg (ovulation).

The luteal cycle begins after ovulation and lasts about two weeks. During this time, the ovaries increase production of both estrogen and progesterone. The hormones prepare the lining of the uterus for implantation with a fertilized egg.

If the egg isn't fertilized, the ovaries stop producing estrogen and progesterone. That, in turn, causes menstruation, or the shedding of the blood and tissue that line the uterus. With that, another cycle begins.

What's the connection between these two hormones and blood sugar?

Estrogen may make your cells more receptive, or sensitive, to insulin. That is, more sugar leaves your bloodstream and enters individual cells, causing the level of sugar in your blood to drop.

Progesterone, on the other hand, may make your cells more resistant to insulin. That means more sugar stays in your bloodstream. The more progesterone released, the more resistant your cells are to insulin, so the more glucose stays in your blood, causing blood sugar levels to rise.

Production of these two hormones varies throughout the menstrual cycle and doesn't always occur simultaneously or to the same degree, so women may be affected differently. But in general, it's during those seven to 14 days before menstrual bleeding begins — during the luteal phase — that some women see fluctuations in their blood sugar levels despite maintaining stable doses of their diabetes medication. Blood sugar generally stabilizes a day or two after the period starts.
