What is diabetes mellitus?

Diabetes mellitus is a metabolic disorder that occurs when your blood sugar (glucose), is too high (hyperglycemia). Glucose is what the body uses for energy, and the pancreas produces a hormone called insulin that helps convert the glucose from the food you eat into energy. When the body does not produce enough insulin - or does not any at all - the glucose does not reach your cells to be used for energy. This results in type 1 and 2 diabetes.
According to the CDC, 30 million (9.4% of the US population), and 7.2 million Americans don't know that they have diabetes.
There are two types of diabetes.
Type 1 diabetes, formerly called juvenile diabetes, is an autoimmune condition in which the body does not produce insulin because the body's immune system attacks insulin-producing cells from the pancreas called beta cells.
Type 2 diabetes is a condition in which cells cannot use blood sugar (glucose) efficiently for energy. This occurs when blood sugar gets too high over time, and the cells become insensitive to insulin.
Prediabetes (sometimes spelled pre-diabetes) is a condition that often precedes type 2 diabetes. Prediabetes is when your blood sugar is higher than normal, but not quite high enough to be diagnosed with diabetes. Prediabetes does not usually have any symptoms so there may be no warning signs. A blood test can confirm if you have prediabetes.
More than 84 million American adults have prediabetes, and about 90% of people don't know that they have it. If a person does not change their diet and lifestyle, prediabetes can become type 2 diabetes within 5 years.
What are the early signs and symptoms in women with diabetes?
Many type 1 and type 2 diabetes symptoms in women are the same as those in men; however, there are some symptoms and complications of diabetes unique to women.
Vaginal itching and pain as well as vaginal and oral yeast infections: An overgrowth of Candida albicans fungus can cause vaginal yeast infections and oral yeast infections (oral thrush). Symptoms of vaginal yeast infections include:
- Vaginal itching and pain
- Vaginal discharge
- Painful sexual intercourse.
Symptoms of oral thrush include:
- White patches in the mouth
- Redness and soreness
- Trouble eating or swallowing
- Swollen red gums or inner cheeks.
5. Decrease in sex drive: Women with diabetes may experience lower sex drive (libido), blood flow problems to the genital area, which can decrease sexual response and orgasm, and nerve damage (diabetic neuropathy) that can result in vaginal dryness and decreased sensation.
6. Polycystic ovary syndrome (PCOS): This is a common cause of female infertility and insulin resistance. It can cause signs and symptoms like irregular periods, acne, thinning scalp hair, and excess hair growth on the face and body. High insulin levels also increase the risk of developing diabetes, and about half of women with PCOS develop diabetes.
7. Urinary tract infections (UTIs): A UTI occurs when bacteria enter anywhere in the urinary tract, including the urethra, ureters, kidneys, and bladder. They are much more common in women than in men in general, and they occur more often in people with diabetes because the sugar in the urine presents a breeding ground for bacterial growth.
What signs and symptoms are the same in men and women?
There are diabetes symptoms that both women and men have in common:
- Excessive thirst and hunger
- Frequent urination
- Weight loss or gain
- Fatigue
- Irritability
- Blurred vision
- Slow-healing wounds
- Nausea
- Skin infections
- Darkening of skin in areas of body creases (acanthosis nigricans)
- Breath odor that is fruity, sweet, or acetone
- Tingling or numbness in the hands or feet
Some complications of type 1 and type 2 diabetes are the same, for example, skin, eye, circulation, low blood sugar (hypoglycemia), high blood sugar (hyperglycemia), ketoacidosis, and amputation.

QUESTION
Diabetes is defined best as... See AnswerWhat if you have diabetes and get pregnant ?
Diabetes need not affect a pregnancy if it is properly controlled. Women with diabetes should talk to their doctor when planning to conceive so they can get blood sugar levels under control before becoming pregnant. You will need to understand how to monitor and control your diabetes and blood sugar levels during pregnancy.
If you have high blood sugar levels during pregnancy, there are risks to both the baby and the mother. High blood glucose levels can result in:
- Premature delivery
- Difficult delivery or cesarean section (C-section)
- Miscarriage
- Preeclampsia (high blood pressure usually with protein in the urine)
- Birth defects
- Having a large baby
- Low blood glucose in a newborn
- Yellowing skin and eyes (jaundice) in a newborn
- Breathing problems in the newborn
- Worsening diabetic eye problems and kidney problems for the mother
- More frequent urinary or bladder infections
What are the signs and symptoms of gestational diabetes?
Doctors will test for gestational diabetes during the 24th to 28th weeks of pregnancy, as this usually is when the condition develops. Often, gestational diabetes has no symptoms, but you may experience some symptoms common to diabetes such as:
- Sugar in the urine (Your doctor can perform a urinalysis to detect this.)
- Increased thirst.
- Frequent urination.
- Fatigue or feeling tired more than usual.
- Nausea.
- Blurred vision.
- Feeling hungrier than usual.
- Weight loss without trying.
- Increased infections (vaginal, bladder, and skin).
- Dry, itchy skin.
- Increase in vaginal yeast and urinary tract infection (UTI).
What are the complications of diabetes during pregnancy?
When diabetes occurs in women during pregnancy, it is called gestational diabetes. It usually is diagnosed between the 24th and 28th weeks of pregnancy. Like in type 1 and type 2 diabetes, blood sugar levels become too high. When women are pregnant, more glucose is needed to nourish the developing baby. The body needs more insulin, which is produced by the pancreas. In some women, the body does not produce enough insulin to meet this need, and blood sugar levels rise, resulting in gestational diabetes.
Fortunately, for most women, gestational diabetes will go away once the baby is born. However, women who have had gestational diabetes are at increased risk for developing type 2 diabetes.
Risk factors for gestational diabetes include:
- Being overweight or obese
- Family history of diabetes
- Ethnicity: higher risk for Hispanics, African Americans, Native Americans, Alaskan Natives, Asian Americans, or Pacific Islanders
- Age over 25
- Previous gestational diabetes, stillbirth or miscarriage, or having a large baby (9 pounds or more)
- Polycystic ovary syndrome (PCOS) or another health condition known to be associated with insulin problems
- Problems with insulin or blood sugar, such as insulin resistance, glucose intolerance, or “prediabetes”
- High blood pressure
- High cholesterol
- Heart disease

Can you die from diabetes?
Men, women, and children can develop diabetes, but the disease can present problems unique to women. A 2007 study found that between 1971 and 2000, death rates for men with diabetes declined, but death rates for women did not.
In general, women live longer than men do because they have a lower risk of heart disease, but when women develop diabetes, their risk for heart disease skyrockets, and death by heart failure is more likely in women than in men. Another study also found that in people with diabetes, heart attacks are more often fatal for women than they are for men. Other examples of how diabetes affects women differently than men are:
Kidney disease is complication of type 1 diabetes, and type 2, that affect women more strongly than men.
Depression is twice as common in women with diabetes as it is in men with diabetes.
Women with diabetes are more prone to poor blood sugar control (which can lead to hyperglycemia and hypoglycemia), obesity, high blood pressure, and high cholesterol than men with diabetes.
There are several reasons suggested for why both type 1 and type 2 diabetes may affect women more dramatically than men:
In women with diabetes, the HDL ("good") cholesterol levels drop, which results in greater heart disease risk, they have less estrogen, and lower levels of estrogen are associated with kidney disease. Women with diabetes may receive less effective health care, particularly for heart disease and heart disease risk factors. Women with diabetes often have polycystic ovary syndrome (PCOS), which is a risk factor for diabetes, and can result in problems getting pregnant.

What should you do if you think that you may have diabetes or prediabetes?
If you notice any of the symptoms of diabetes, see your doctor. If diabetes is untreated, it can lead to serious complications including heart disease, stroke, high blood pressure, blindness, kidney disease, and nerve damage.
Your doctor will check your blood glucose levels, and if you are diagnosed with diabetes, your doctor will guide you on a plan to keep your blood sugar levels normal. If your diabetes is mild, your doctor will likely recommend a diet plan, exercise, and weight loss. Your doctor may prescribe medications that help reduce blood sugar levels. In some women, insulin may be necessary.

The heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.Hemoglobin A1c Test
Hemoglobin A1c or HbA1c is a protein on the surface of red blood cells. The HbA1c test is used to monitor blood sugar levels in people with type 1 and type 2 diabetes over time. Normal HbA1c levels are 6% or less. HbA1c levels can be affected by insulin use, fasting, glucose intake (oral or IV), or a combination of these and other factors. High hemoglobin A1c levels in the blood increases the risk of microvascular complications, for example, diabetic neuropathy, eye, and kidney disease.Low Blood Sugar (Hypoglycemia)
Low blood sugar or hypoglycemia occurs when blood sugar is dangerously low and is often complication of type 1 and type 2 diabetes. Learn about symptoms, dangers, and treatment.Normal Blood Sugar Levels In Adults with Diabetes
People with diabetes can manage and prevent low or high blood sugar levels (hyperglycemia or hypoglycemia) by keeping a log of your blood sugar levels when you are eating and fasting and eat foods that are high in carbohydrates and sugar, for example, buttered potatoes, candy, sugary desserts, and fatty foods.
Blood tests, for example, the hemoglobin A1c test (A1c test) and urinalysis can diagnose the type of diabetes the person has. Diabetes during pregnancy, called gestational diabetes, should be managed by you and your OB/GYN or another healthcare professional.
Extremely high levels of blood glucose in the blood can be dangerous and life threatening if you have type 1, type 2, or gestational diabetes.
If you or someone that you are with has extremely high blood glucose levels, call 911 or go to your nearest Urgent Care or Emergency Department immediately.
To prevent and manage high blood glucose levels in people with diabetes keep a log of your blood sugar levels, eat foods that are high in carbohydrates sugar, for example, buttered potatoes, candy, sugary deserts, and fatty foods that you can share with your doctor and other healthcare professionals.

Transmetatarsal amputation (TMA) involves surgical removal of a part of the foot that includes the metatarsals. TMA is a relatively common operation performed to treat a severely infected foot or a foot with lack of oxygen supply (ischemic). Surgeons resort to this type of surgery when all other nonsurgical options to save the foot or limb have failed. Removing the infected part prevents the infection from spreading to the other parts of the limb and thus saves the limb in the long run.When Are Wrist and Forearm Amputations Performed?
Surgical removal of the wrist and forearm is performed in patients with conditions such as severe injury with irreplaceable loss of blood supply to the wrist or/and forearm; diseases such as peripheral vascular disease [PVD] (blood vessel disease), diabetes, blood clots, or sepsis (severe infection); burns, thermal injuries, and injury secondary to extreme cold exposure to the wrist or/and forearm; surgery to remove tumors or infected area from the bones and muscle, ulcers, and pathological fractures.
