Ngaphambi kokuba umzimba wakho uzuze kunoma imuphi umsoco odlayo, i-tract yakho yomzimba kufanele igaye futhi ibambe ukudla okudlayo. Kodwa ngaphambi kokuba udle, kusiza ukulamba.
Ukulamba umuzwa owutholayo lapho umzimba wakho udinga ukudla. Uma usenele ngokwanele ukudla, akufanele uphinde ulambe. Kungenxa yokuthi ama-hormone ahlukahlukene alawula ukulamba:
Leptin. I-hormone eyimfihlo yesikhumba (amafutha) e-adipose (amafutha) egazini lakho. Amafutha amaningi emzimbeni wakho aphakamisa amazinga egazi lakho leptin. Izinga lakho leptin landa futhi ngokudla futhi liphakeme kakhulu kwabesifazane kunamadoda, kodwa jikelele, liyancipha njengoba ukhula. Amazinga we-leptin akhula aqala i-hypothalamus ukunciphisa indlala.
I-Ghrelin. I-hormone eyenziwa yisisu nesisu esincane uma isisu sakho singenalutho. Njenge-leptin, ibuye isebenze ne-hypothalamus, kodwa esikhundleni sokucindezela indlala, yandisa indlala.
Adiponectin. I-hormone ifihlwe ngamaseli amafutha emzimbeni wakho. Kodwa njengoba izinga lakho lamafutha omzimba liwela phansi, leli hormone likhuphuka futhi ngokuphambene; uma uthola amanoni, amazinga akho e-adiponectin ahla.
Cholecystokinin. Le hormone ikhiqizwa emathunjini amancane ngesikhathi nangemva kokudla. Lokhu kubangela ukukhululwa kwe-bile ne-enzymes yokugaya inyama emathunjini amancane, futhi kuthintela indlala futhi kukuzwe uzizwe ugcwele.
I-Peptide YY. Ukwenziwa ngamathumbu amakhulu nangamancane emva kokudla, le hormone igcizelela ukudla kwakho cishe amahora angu-12 ngemuva kokudla.
I-insulini. Ama-pancreas akhiqiza leli hormone. Kuyaziwa kahle ngokulawula amazinga kashukela egazini. Iphinde igxila indlala.
Glucocorticoids. Lawa mahomoni ayenziwa ngama-gland akho, futhi umsebenzi wabo oyinhloko ukulawula ukuvuvukala nezinye izinqubo, kodwa futhi banomthelela wendlala.
Ukuntuleka kwe-cortisol kunciphisa ukudla, kodwa inani eliningi kakhulu le-glucocorticoids landa ukoma.
Indlala ngokumelene nokudla - Kukhona umehluko
Ukulamba akufani nokudla. Ukulamba kuyisisindo sangempela ngenxa yezinguquko zamakhemikhali emzimbeni wakho ngenxa yesidingo sokudla okungaphezulu ngenkathi ukudla kunomqondo ongokwemvelo. Ukudla yisinye sezizathu zokuthi ungadla kakhulu uma ungalambile.
Manje ukuthi ulambile, sekuyisikhathi sokudla. Ukugaya kuhlanganiswa futhi kulawulwa amahomoni amaningana:
I-Gastrin . I-hormone ekhishwe yisisu nomathumbu omncane uma udla. I-Gastrin ivuselela ukukhipha i-hydrochloric acid ne-pepsinogen esiswini, futhi ishesha ukugaya. Futhi, i-gastrin ivuselela i-glucagon, i-hormone esebenza nge-insulin ukuze ilawule ushukela wegazi.
Secretin . I-hormone eyenziwe emathunjini amancane futhi ifihlelwe ekusakazweni kwegazi lapho i-chyme acidic isuka esiswini ifika emathunjini amancane. I-Secretin igqugquzela ama-pancreas ukukhulula ama-juice okugcoba ama-bicarbonate e-intestine encane. I-bicarbonate ayitholi i-acidity ye-chyme. I-Secretin yenza isisu ukuze iqale ukukhiqizwa kwe-pepsinogen ukusiza ukuphula amaprotheni, futhi kungase futhi kwehlisa inqubo yokugaya ukudla, okungenani endaweni yesisu nangengxenye yokuqala yomathumbu amancane.
I-Cholecystokinin (CCK). Amathumbu akho amancane enza futhi akhiphe iCCK ekusakazweni kwegazi lakho. Kubalulekile ukugaya amanoni ngoba kuvuselela i-gallbladder ukukhipha ibhala emathunjini amancane. Iphinde ibangele ama-pancreas ukukhulula ama-enzyme awo ahlukahlukene wokugaya emathunjini amancane ukuze aphule amafutha, ama-carbohydrate, namaprotheni.
I-Motilin. Enye i-hormone eyenziwe ngamathumbu amancane. I-Motilin iqinisa umsebenzi ngaphakathi esiswini nasezintweni ezincane. Iphinde igqugquzele isisu ne-pancreas ukukhulula imfihlo ehlukahlukene futhi kubangele ukuthi i-gallbladder ivumelane.
I-peptide insulinotropic exhomeke ku-glucose (GIP). Le hormone yenziwa ngamathumbu amancane.
Ivuselela ama-pancreas ukukhulula i-insulini futhi iyanciphisa umsebenzi wokugaya esiswini. I-hormone ngezinye izikhathi ibizwa ngokuthi i-peptide yokuvimbela isisu.
I-Peptide YY ne-enterogastrone. Ama-hormone amabili amabili akhiphe isisu esincane esinciphisa ukugaya nokunciphisa ukukhiqizwa kwemfihlo yokugaya ukudla.
