Diabetes: Breast-feeding May Help Babies and Women Against Diabetes
Babies and women may be protected against developing diabetes disease through breast feeding, according to new research. This current study states that the longer women nursed, the lower their risks of developing diabetes.
Diabetes as a medical disorder characterized by varying or persistent elevated blood sugar levels, especially due to eating, is a serious disease which symptoms are very similar for all types of diabetes.
Breast feeding is when a woman feeds a baby or a young child with milk produced from her breasts. The best thing for feeding a baby is breast milk, as experts say, if the mother does not have transmissible infections.
Although study findings are not conclusive, researchers explain that breast-feeding may change metabolism of mothers which may help keep blood sugar levels stable and make the body more sensitive to the blood sugar-regulating hormone insulin.
This theory is based on some evidence that show that in rats and humans that are breast-feeding, mothers have lower blood-sugar levels than those who did not breast-feed.
According to the study published in the Journal of the American Medical Association, women who breast-fed for at least one year were about 15 per cent less likely to develop diabetes type 2 than those who never breast-fed. For each additional year of breast-feeding, there was an additional 15 per cent decreased risk.
A total of 157,000 nurses participated in the new study. They answered periodic health questionnaires and were followed for at least 12 years. During the study, 6,277 participants developed type 2 diabetes.
Diabetes: Diabetic Foot Ulcers May be Cure by A Vitamin A Compound
A compound of vitamin A called topical Retin-A also known as tretinoin, mainly used to treat acne problems, enhances the healing of foot ulcers in patients with diabetes, according to a report of the Archives of Dermatology.
Though previous studies showed that topical Retin-A was a bit helpful in enhancing wound healing in patients with diabetes and some results were discussed by different scientifics, a group of researchers tried to know if tretinoin really helped or not to these patients.
The research was carried out with 24 volunteers who had diabetic foot ulcers but who showed no evidence of infection or circulation problems in their extremities. Some patients were assigned to 4 weeks of daily treatment with topical 0.05 per cent tretinoin solution meanwhile the control group was assigned to a treatment with a saline solution. Both groups were assessed every 2 weeks.
The 22 volunteers who completed the study were affected by a total of 24 foot ulcers. 18 per cent of patients in the control group (2 of the 11 ulcers) and 46 per cent of patients in the treated group (6 of the 13 ulcers) achieved a complete healing at the end of 16 weeks. There was no statistical significance of adverse events, though some patients experienced mild pain at the ulcer site.
The researchers were pleased with the results, although they were a bit concerned because tretinoin irritates and they thought that the patients would become so irritated that they wouldn't be able to continue the research. However, this situation didn't seem to be a problem in most cases, as they explained.
A conclusion for the researchers was that they hope that diabetic foot clinics know about this and use Retin-A when other therapies that they use don't work.
Diabetes: Diabetics Should Not Have A High Carb Diet Due To Blood Pressure
New studies evaluating the effects of high-carbohydrate and high- monounsaturated fat diets indicate that patients with type 2 diabetes suffered of modestly raises blood pressure after being exposed to 14 weeks of a high-carbohydrate diet compared to a diet high in monounsaturated fat.
One diet consisted in a high-carbohydrate diet consisting of 55 per cent of calories as carbohydrate, 30 percent as fat, and 10 percent as monounsaturated fat. The other diet consisted in a high-monounsaturated fat diet deriving 40 percent of calories from carbohydrate, 45 percent from fat, and 25 percent from monounsaturated fat.
The research compared the effect of two same-calorie diets among 42 patients with type 2 diabetes, who consumed each diet for 6 weeks, with about 1 week between the two periods. These patients were invited to continue the second diet for 8 weeks more. Eightof them continued on the high-monounsaturated fat diet and 13 continued on the high-carbohydrate diet.
Findings after the first 6-week periods demonstrated that there were no significant differences between both diets in systolic or diastolic blood pressure, the upper and lower numbers on a standard reading, respectively, or in heart rate.
After the 8 week-extension, diastolic blood pressure was 7 points higher than at the end of both 6-week phases, because of the high carbohydrate diet associated, and systolic blood pressure was 6 points higher, and heart rate was higher by 7 to 8 beats per minute.
On the other hand, there was a significant lowering of heart rate compared with the end of the initial 6-week periods during the 8-week extension of the high-monounsaturated fat diet. There was almost no statistical significance between Systolic and diastolic blood pressure that were 3 to 4 points lower after 14 weeks on the high-monounsaturated fat diet.
Diabetes: Eating Healthy, Eating Well!
Types Of Diabetes
There are two types of diabetes, and they really are two quite different diseases. In type 1, or insulin-dependent diabetes, insulin injections are needed. But in type 2, or non-insulin-dependent diabetes, most people can keep their condition under control with just diet and medication. This type of diabetes is actually much more common than the insulin-dependent type.
How do I find out which type of diabetes I have?
Your doctor will tell you what type of diabetes you have and what you need to do. You can also ask your doctor to refer you to a Diabetes Education program. There, trained health professionals can teach you about diabetes and insulin.
What Is Insulin?
Insulin is classified according to how long it works in the body. There are five different types of insulin, ranging from short to long acting. Some insulins are clear in appearance, while others are cloudy.
Types of insulin
The five types of insulin include:
1. Rapid onset-fast acting insulin
2. Short acting insulin
3. Intermediate acting insulin
4. Mixed insulin
5. Long acting insulin.
Diabetes And Healthy Eating
Healthy eating, combined with regular physical activity and weight control, is important to manage diabetes.
People with diabetes should eat mainly high fibre carbohydrate foods such as wholegrain breads and cereals and vegetables and fruit. They should also reduce their intake of fat, especially saturated fat. Limiting the serving size of your meals is often required to maintain a healthy body weight. It’s also a good idea to see a dietitian who can help develop a healthy eating plan.
Healthy eating helps a person with diabetes to:
1. Maintain general good health
2. Control blood glucose levels
3. Achieve normal blood lipid (fat) levels
4. Maintain a healthy blood pressure
5. Maintain a healthy body weight
6. Prevent the complications of diabetes.
No Special Diets Required
Healthy eating for people with diabetes is no different than for everyone else. People with diabetes do not need to prepare separate meals or buy special foods, so relax and enjoy healthy eating with the rest of your family.
Diabetes, Glaucoma Put Millions At Risk for Unexpected Blindness
Unexpected sight loss is more common than you may think. Blindness often happens without prior warning signs and in people unaware they are at risk.
The two most common culprits of unexpected sight loss are diabetes and glaucoma. These diseases are known as the "sneak thieves of sight" because symptoms may not occur in the early stages. By the time a person realizes something is wrong, irreversible vision loss often occurs.
In fact, diabetic eye disease is the leading cause of blindness in adults. An average of 55 Americans go blind from the disease each day. The numbers threaten to rise sharply as diabetes becomes increasingly common due to poor eating habits, infrequent exercise and an aging population. One in three children born in the United States five years ago are expected to become diabetic during their lives.
Diabetes causes partial or complete loss of vision in as many as 70 percent of those who have it. Yet 30 percent of all people who have diabetes don't even know they have it. Even people who know they have diabetes downplay the risks they face.
According to a survey of diabetics sponsored by Lions Clubs International, 60 percent were not worried about going blind or losing a limb. In reality, 74 percent of diabetics will develop serious complications that could lead to loss of sight or a limb or kidney failure.
Glaucoma, on the other hand, is a group of eye diseases that slowly damage the fine nerves that connect the eye to the brain. For most people, this damage occurs when pressure in the eye is too high. When these nerves are damaged, vision loss may result.
Glaucoma is the second-leading cause of blindness in the United States. But like diabetes, not enough people know about it: An estimated 4.2 million Americans have glaucoma but half are not aware of it.
Diabetes and glaucoma are especially prevalent among blacks and Hispanics. These groups are believed to have a genetic predisposition to the diseases and are much more at risk than Caucasians. Others particularly at risk for glaucoma are people over 60, those with a family history of glaucoma, diabetics and the very near-sighted.
The good news for those at risk is that a dilated eye exam can detect the two diseases and early treatment can prevent vision loss. Vision experts urge at-risk people to have regular eye exams.
Raising awareness of diabetic eye disease and glaucoma is key to preventing unnecessary blindness. Lions Clubs International works with Lions clubs, community groups and individuals to publicize the need for early detection and timely treatment of the two diseases. The Lions Eye Health Program provides materials for distribution at health fairs, senior citizen centers and similar gatherings. It also offers strategies for raising awareness of the eye diseases.
