I-hormone leptin ikhiqizwa ngama-fat fat cells. Ngenye indlela, ibizwa nangokuthi i-hormone e-satiety, i-hormone yokulawula ukudla, i-hormone-calorie burner.
I-leptin isebenza kanjani?
Ngemva kokudla, amangqamuzana amathishu amafutha athumela i-leptin esifundeni sobuchopho, okuthiwa yi-hypothalamus, enesibonakaliso sokuthi umzimba ugcwele, amafutha amaningi agcwaliswa. Ephendula, ubuchopho buyathumela umyalo wokunciphisa ukudla futhi ukwandise ukusetshenziswa kwamandla. Ngenxa yalokhu, ukuguqula umzimba okuvamile kwenzeka , izinga le-glucose elihle ligcinwa ekuthuthukiseni amandla.
Lokhu kusho ukuthini uma i-hormone leptin iphakanyisiwe?
Abantu abaningi abahlushwa ukukhuluphala banesimiso sokuqaphela ubuchopho be-hormone leptin. Lokhu kusho ukuthi emva kokuba umuntu ethathe ukudla, amangqamuzana amabi athumela umlayezo we-hypothalamus wokuthi indlala yanelisekile. I-Leptin ifika ebuchosheni, kodwa ayitholi impendulo. Ubuchopho buyaqhubeka "becabanga" ukuthi umuzwa wendlala ukhona futhi unikeza umyalo wokuqhubeka ugcwalisa izimpahla ezidliwayo - ukudla akunciphisi, umuzwa wendlala uyaqhubeka, futhi umuntu uqala ukudla ngokweqile. Amangqamuzana amafutha aqhubeka nokukhiqiza i-leptin ukuze "aphume" ebuchosheni. Ngenxa yalokho, okuqukethwe kwe-leptin egazini kuyanda.
Iziphi izimo i-leptin eyanda ngayo?
Ucwaningo lwesayensi luye lwabonisa ukuthi izinga leptin linganda ezinkathini ezinjalo:
- ngesikhathi sokuya esikhathini;
- ngesikhathi sokukhulelwa;
- ngesikhathi sokuya esikhathini;
- ne-polycystic ovary syndrome (PCOS);
- emva kokuqedwa kokufakelwa;
- ngesikhathi sokukhulelwa emantombazaneni.
Yini eyongela ukwanda kwe-hormone leptin egazini?
Uma kubonisiwe ukuthi i-leptin iphakeme kunejwayelekile, lezi zenzakalo ezilandelayo zingabonakala:
- ukucindezela ukukhiqizwa kwe-pancreas ye-insulini, okuholela ekuthuthukiseni isifo sikashukela mellitus ;
- kunciphisa ukuqina kwezindonga zegazi, imishanguzo;
- i-thrombi yakhiwa;
- izifo ezihlukahlukene zesimiso senhliziyo zikhula.
Enye yezindlela ezivame ukubhubhisa isenzo esivamile se-hormone leptin yizidlo ezihlukahlukene.
