Ke Koʻikoʻi o ka Waikawa Gastric i ke Kaʻina Hana Digestive
ʻO ka waikawa ʻōpū, i ʻike nui ʻia ma ke ʻano lapaʻau ʻo ka waikawa hydrochloric (HCl), he ʻāpana koʻikoʻi ia o ka ʻōnaehana hoʻoheheʻe kanaka. ʻOiai ua manaʻo pinepine ʻia he kumu e kōkua ai i ka ʻeha a me nā maʻi e like me ka ʻeha puʻuwai a me nā ʻōpū, he kuleana koʻikoʻi ka waikawa ʻōpū i ka hōʻoia ʻana i ka ʻeli mālie ʻana o ka meaʻai a mākou e ʻai ai i kēlā me kēia lā. Ma kēia ʻatikala, e kūkākūkā kikoʻī mākou i ke koʻikoʻi o ka waikawa ʻōpū i ke kaʻina hana hoʻoheheʻe, kāna mau hana hana, a pehea e hiki ai i kahi kaulike ʻole i ka hana ʻana o ka waikawa ʻōpū ke hoʻopilikia i ko mākou olakino.
Ka Hana o ka Waikawa Gastric i ka ʻŌmole ʻAna
1. Ka Hoʻokaʻawale ʻAi
He kuleana koʻikoʻi ko ka waikawa ʻōpū i ka wāwahi ʻana i nā molekala meaʻai nui i nā ʻāpana liʻiliʻi a maʻalahi hoʻi e ʻeli ʻia. Ke ʻai mākou, hele ka meaʻai ma o ka esophagus a i loko o ka ʻōpū, kahi e hoʻomaka ai ka hana o ka waikawa hydrochloric. Hoʻopau kēia waikawa i nā ʻiʻo pili i loko o ka ʻiʻo, hoʻopau i nā molekala protein i loko o ka meaʻai i loko o nā kaulahao peptide liʻiliʻi, a kōkua i ka hoʻoheheʻe ʻana o ka momona.
2. Hoʻāla ʻia o nā Enzymes Digestive
ʻO ka waikawa ʻōpū kekahi kuleana no ka hoʻoulu ʻana i nā enzyme digestive. ʻO kahi enzyme koʻikoʻi i hoʻoulu ʻia e ka waikawa ʻōpū ʻo ia ka pepsinogen, kahi i hoʻololi ʻia i pepsin i loko o kahi ʻano waikawa. ʻO Pepsin kahi enzyme e wāwahi i nā protein i loko o nā peptides liʻiliʻi, a laila e hoʻoheheʻe hou ʻia i loko o ka ʻōpū liʻiliʻi.
3. Ka palekana ʻana mai nā microorganism pathogenic
He mau waiwai antibacterial ikaika ko ka waikawa ʻōpū, e kōkua ana i ka pale ʻana i ka ʻōnaehana hoʻoheheʻe mai ka maʻi. Hiki i nā pathogens he nui ke komo i ke kino ma o ka meaʻai a me ka mea inu a mākou e ʻai ai. Eia nō naʻe, hiki i ke kaiapuni waikawa i loko o ka ʻōpū ke pepehi i ka hapa nui o kēia mau microorganism, no laila e pale ana i nā maʻi a me nā maʻi ʻōpū ʻē aʻe.
4. Ka Hoʻopili ʻana o ka Mineral
He kuleana ko ka waikawa ʻōpū i ke kōkua ʻana i ka omo ʻana o nā minelala koʻikoʻi like ʻole, e like me ka calcium, magnesium, a me ka hao, i loko o nā ʻōpū. Kōkua kēia waikawa i ka hoʻokuʻu ʻana i nā minelala mai ka meaʻai i hiki ke omo ʻia e ke kino me ka maikaʻi.
ʻAno Hana Hana ʻAkika Gastric
Hoʻomaka ka hana ʻana o ka waikawa gastric i loko o nā cell parietal i loko o ka paia o ka ʻōpū. Hoʻokuʻu kaʻawale kēia mau cell i nā ion hydrogen (H+) a me chloride (Cl-), a laila hui pū e hana i ka HCl i loko o ka lumen o ka ʻōpū. Hoʻomalu ʻia kēia kaʻina hana e nā hormones like ʻole a me nā hōʻailona aʻalolo e pane ana i ke alo o ka meaʻai.
1. ʻO Gastrin
He hormone ʻo Gastrin i hana ʻia e nā pūnaewele G i loko o ka antrum o ka ʻōpū. Hoʻoulu kēia hormone i nā pūnaewele parietal e hana i ka waikawa gastric a hoʻonui pū i ka neʻe ʻana o ka gastric, e hoʻomākaukau ana i ke kino no ka meaʻai.
2. Histamine
ʻO ka Histamine, ka mea i hoʻokuʻu ʻia e ECL (nā pūnaewele enterochromaffin-like), hana ia e hoʻoulu i nā mea loaʻa H2 ma nā pūnaewele parietal, no laila e hoʻonui ai i ka hana ʻakika gastric.
3. ʻAsetilokolina
Hoʻokuʻu ʻia ka Acetylcholine e ke aʻalolo vagus ma muli o ka hoʻoulu ʻia ʻana mai ka ʻono a me ke ʻala o ka meaʻai. Hoʻoulu pū ia i nā pūnaewele parietal e hana i ka HCl.
Nā Maʻi i Hoʻokumu ʻia e ke Kaulike ʻAkika ʻŌpū
ʻO ke kaulike ʻole o ka hana ʻana o ka waikawa o ka ʻōpū hiki ke alakaʻi i nā ʻano maʻi ʻōpū like ʻole, ʻo ka hapa nui o ia mau mea he mea koʻikoʻi loa inā ʻaʻole mālama pono ʻia.
1. Ka maʻi Reflux Gastroesophageal (GERD)
ʻO GERD kahi kūlana e kahe hou ai ka waikawa o ka ʻōpū i loko o ka esophagus, e hana ana i kahi ʻano wela i ʻike ʻia ʻo ka heartburn. Hana ʻia kēia ke pani pono ʻole ka sphincter esophageal haʻahaʻa.
2. ʻAʻai ʻōpū
ʻO ka gastritis kahi mumū o ka uhi ʻōpū i hiki ke hana ʻia e nā kumu like ʻole, me ka maʻi Helicobacter pylori, ka inu ʻona, a me ka hoʻohana lōʻihi ʻana i nā lāʻau anti-inflammatory nonsteroidal (NSAID). ʻO ka hana nui ʻana o ka waikawa ʻōpū a i ʻole ke kaulike ʻole hiki ke hoʻonui i kēia kūlana.
3. ʻUlu ʻōpū a me ka ʻUlu Duodenal
ʻO nā ʻeha ʻōpū a me nā ʻeha duodenal he mau ʻeha hāmama e ulu ana ma ka ʻaoʻao o loko o ka ʻōpū a i ʻole ka hapa mua o ka ʻōpū liʻiliʻi (duodenum). Hiki ke hana ʻia e ka nui o ka waikawa ʻōpū, ka maʻi H. pylori, a i ʻole ka hoʻohana lōʻihi ʻana i nā NSAID.
4. Hypochlorhydria
ʻO ka Hypochlorhydria kahi kūlana e hoʻemi ʻia ai ka hana ʻana o ka waikawa o ka ʻōpū, hiki ke hoʻoulu i nā pilikia ʻōnaehana hoʻoheheʻe like ʻole e like me ka pehu ʻana, ke kinoea, a me ka malabsorption o nā meaola, ʻoiai ka protein a me nā minelala.
Ka Lapaʻau a me ka Kāohi ʻana
1. Nā lāʻau lapaʻau
Nā Antacids: Loaʻa nā mea hoʻohui e like me ka magnesium hydroxide a me ka alumini hydroxide e hoʻopau i ka waikawa o ka ʻōpū;
Nā mea pale o ka pamu proton (PPI): E hōʻemi i ka hana ʻakika o ka ʻōpū ma ke kāohi ʻana i ka enzyme e hana ana i ka HCl (e.g. omeprazole, lansoprazole);
Nā Mea Pale i ka H2 Receptor: E hōʻemi i ka hana ʻakika gastric ma ke ālai ʻana i nā mea hoʻokipa histamine (e.g. ranitidine, famotidine).
2. Nā Hoʻololi o ke ʻAno Nohona
– ʻAi Kaulike: E hōʻalo i kekahi mau meaʻai e hiki ke hoʻoulu i ka hana nui ʻana o ka waikawa o ka ʻōpū e like me ka caffeine, ka waiʻona, nā meaʻai ʻala, a me nā meaʻai momona.
– Kaumaha Kino Kūpono: E mālama i ke kaumaha o ke kino olakino e hōʻemi i ke kaomi ma ka ʻōpū a me ka pilikia o GERD.
- Hōʻalo i ka puhipaka: Hiki i ka puhipaka ke hōʻino i ka sphincter esophageal haʻahaʻa a hoʻonui i ka pilikia o ka reflux acid.
3. Hoʻokele Koʻikoʻi
Hiki i ke kaumaha ke hoʻonui i ka hana ʻakika o ka ʻōpū a hoʻonui i nā maʻi e like me ka gastritis a me ka GERD. Hiki i nā ʻano hana hoʻokele kaumaha e like me ka noʻonoʻo ʻana, ka yoga, a me ka hoʻomaha ʻana ke kōkua i ka kaohi ʻana i ka hana ʻakika o ka ʻōpū.
Ka hopena
He mea nui ka waikawa ʻōpū e pāʻani ana i kahi kuleana koʻikoʻi i ke kaʻina hana ʻai. Ma waho aʻe o ke kōkua ʻana i ka wāwahi ʻana i ka meaʻai a me ka hoʻoulu ʻana i nā enzymes digestive, hana pū ia ma ke ʻano he laina pale mua e kūʻē i nā pathogens e komo ana i ka ʻōnaehana digestive. Eia nō naʻe, ʻo ka nele o ka hana ʻana o ka waikawa ʻōpū hiki ke alakaʻi i nā pilikia olakino like ʻole e pono ai ke kōkua lapaʻau. Ma ka hoʻomaopopo ʻana i nā ʻano hana a me nā hana o ka waikawa ʻōpū, hiki iā mākou ke hana i nā hana kūpono e mālama i ke olakino digestive a pale i nā maʻi like ʻole.
