August 24, 2006Kava varuje pred nastankom diabetesaZnanstveniki še vedno ne vedo, katera sestavina kave varuje pred boleznijoZdravje, 5. julij 2006 10:10RTV SLOUživanje kave, tudi brezkofeinske, naj bi zmanjševalo nevarnost pred sladkorno boleznijo, so odkrili ameriški znanstveniki iz univerze Minnesota.Študija, ki so jo objavili v časopisu Arhivi interne medicine, sicer ni prva, ki dokazuje povezanost kave in sladkorne bolezni. Pri prejšnjih raziskavah ni bilo znano edino, kakšna je povezava pri ljudeh različnih starosti in različne telesne teže ter ali je kofein tista sestavina kave, ki je v prvi vrsti odgovorna za zmanjšanje nevarnosti, da obolimo za sladkorno boleznijo.Raziskovalna ekipa je analizirala podatke 28.812 žensk, ki so jih dobili med letoma 1986 in 1997. Te ženske na začetku raziskave niso zbolele za sladkorno boleznijo ali katero od srčnih bolezni. Anketiranke so raziskovalci razdelili v več skupin: tiste, ki kave ne pijejo, tiste, ki jo pijejo manj od skodelice dnevno, v tretji skupini so bile tiste ženske, ki spijejo do tri skodelice kave dnevno, v četrti so bile tiste, ki spijejo od štiri do pet skodelic kave na dan, v zadnji skupini pa so bile tiste, ki spijejo nad šest skodelic kave dnevno.Več skodelic kave – manjše tveganjeMed raziskavo so znanstveniki 1.418 ženskam postavili diagnozo – sladkorno bolezen. Raziskovalci so ugotovili, da je bila verjetnost, da bodo za njo zbolele ženske, ki pijejo več kot šest skodelic kave, kar 22 odstotkov manjša kot pri tistih ženskah, ki kave sploh ne pijejo. Nadaljnja raziskava je pokazala, da je povezanost med nevarnostjo obolenja in pitjem kave relativno enaka, ko je govor o starosti in telesni teži. Na povezanost pa je vplivalo tudi pitje kave brez kofeina.Katera sestavina kave varuje pred diabetesom?Znanstveniki pa tudi tokrat niso odkrili, katera sestavina kave je tista, ki varuje pred obolenjem. Dve sestavini kave – magnezij in fitat – nista imela nobenega učinka na povezanost med boleznijo in pitjem kave, prav tako na zmanjšanje ni vplival vnos kofeina v telo iz drugih virov, na primer brezalkoholnih pijač.Neka prejšnja raziskava, ki so jo izvedli na Finskem, ki ima največjo porabo kave na prebivalca na svetu, je pokazala, da imajo moški in ženske, ki popijejo najmanj 10 skodelic kave na dan, najmanj možnosti, da bi zboleli za sladkorno boleznijo.

August 24, 2006Complications of diabetes
Both forms of diabetes ultimately lead to high blood sugar levels, a condition called hyperglycemia. Over a long period of time, hyperglycemia damages the retina of the eye, the kidneys, the nerves, and the blood vessels. * Damage to the retina from diabetes (diabetic retinopathy) is a leading cause of blindness. * Damage to the kidneys from diabetes (diabetic nephropathy) is a leading cause of kidney failure. * Damage to the nerves from diabetes (diabetic neuropathy) is a leading cause of foot wounds and ulcers, which frequently lead to foot and leg amputations. * Damage to the nerves in the autonomic nervous system can lead to paralysis of the stomach (gastroparesis), chronic diarrhea, and an inability to control heart rate and blood pressure with posture changes. * Diabetes accelerates atherosclerosis, or the formation of fatty plaques inside the arteries, which can lead to blockages or a clot (thrombus), which can then lead to heart attack, stroke, and decreased circulation in the arms and legs (peripheral vascular disease). * Diabetes predisposes people to high blood pressure and high cholesterol and triglyceride levels. These independently and together with hyperglycemia increase the risk of heart disease, kidney disease, and other blood vessel complications.In the short run, diabetes can contribute to a number of acute (short-lived) medical problems. * Many infections are associated with diabetes, and infections are frequently more dangerous in someone with diabetes because the body’s normal ability to fight infections is impaired. To compound the problem, infections may worsen glucose control, which further delays recovery from infection. * Hypoglycemia, or low blood sugar, occurs from time to time in most people with diabetes. It results from taking too much diabetes medication or insulin (sometimes called insulin reaction), missing a meal, doing more exercise than usual, drinking too much alcohol, or taking certain medications for other conditions. It is very important to recognize hypoglycemia and be prepared to treat it at all times. Headache, feeling dizzy, poor concentration, tremors of hands, and sweating are common symptoms of hypoglycemia. You can faint or have a seizure if blood sugar level gets too low. * Diabetic ketoacidosis is a serious condition in which uncontrolled hyperglycemia (usually due to complete lack of insulin or a relative deficiency of insulin) over time creates a buildup in the blood of acidic waste products called ketones. High levels of ketones can be very harmful. This typically happens to people with type 1 diabetes who do not have good blood glucose control. Diabetic ketoacidosis can be precipitated by infection, stress, trauma, missing medications like insulin, or medical emergencies like stroke and heart attack. * Hyperosmolar hyperglycemic nonketotic syndrome is a serious condition in which the blood sugar level gets very high. The body tries to get rid of the excess blood sugar by eliminating it in the urine. This increases the amount of urine significantly and often leads to dehydration so severe that it can cause seizures, coma, even death. This syndrome typically occurs in people with type 2 diabetes who are not controlling their blood sugar levels or have become dehydrated or have stress, injury, stroke, or medications like steroids.
