Too Young for Early Menopause Symptoms?

Because doctors are finally beginning to recognize early menopause symptoms in younger women, more and more women are being diagnosed with early or premature menopause. As a result, women who are experiencing infertility or are dealing with menopause symptoms at a young age no longer have to wonder why. Generally, we are unable to determine a cause for early menopause symptoms in younger women. This is frustrating for women as it makes it difficult to accept and deal with this new stage of life. Sometimes though, there are very obvious causes of premature or early menopause.

Early menopause symptoms are essentially the same as those of signs of menopause naturally. Women commonly suffer from night sweats, hot flashes, insomnia, headaches, and joint or muscle pain. Body shape changes are also common, causing you to put on weight around the abdomen. Additionally, water retention and menopause commonly go together.

Early menopause symptoms that women can experience are emotional ups and downs, including anxiety, depression, cravings, and forgetfulness. The reason for night sweats symptoms are triggered by the fluctuation of hormones in the body during menopause. In particular, estrogen levels reduce dramatically during the onset of menopause, causing a variety of changes in the body's functions.

Early menopause symptoms tend to be associated with more severe menopause symptoms than menopause occurring after the age of 45. Because early menopause is often due to illness, surgery, or genetic issues, there is a rapid decline in the amount of estrogen (known as "estrogen crash") in your body. This causes you to enter menopause more quickly than other women. Estrogen crash can cause extreme hot flashes, fatigue, mood swings, and depression in some women. In a survey of early menopause symptoms, 100% of women who experienced surgical menopause experienced a number of menopause symptoms in quick succession. 90% of these women complained that their symptoms were severe and lasted more than 8 years.

Unfortunately, there are no early menopause symptom cures. Menopause information has progressed by leaps and bounds over the years, though. It is suggested that most women who have undergone early or premature menopause seek out hormone replacement therapy (HRT) or, alternatively, natural hormone replacement therapy. Menopause symptoms will be very sudden and severe, especially after surgery, and can be lessoned by taking appropriate doses of estrogen. If oral medication is too difficult to take directly after surgery, estrogen patches that release hormones through the skin can be used to help lessen symptoms.

Then there are very early menopause symptoms, however, not all that typical. Very early menopause symptoms can be caused by a lot of things; this includes the following:

1. Premature ovarian failure. Your ovaries failed, therefore, resulting in early menopause symptoms. The common reason for this is because the woman's body is not responding to the signals to ovulate any longer.

2. Surgery or cancer treatments. A woman can get early menopause if she has subjected herself to certain treatments, usually of cancer.

3. Diminished Ovarian Reserve. This usually occurs to women before the age of 40. This stage is termed as the diminished ovarian reserve.

Very early menopause can be a problem, but only if you make it so; don't let it make you feel any less of a woman than you are now. A woman is not determined by her monthly cycles, but her ability to face life and all that comes with it. Facing this challenge with a good attitude and menopause information makes you stronger than ever.

How are early menopause symptoms confirmed as menopause? The most important test used to diagnose premature menopause is a blood test that measure follicle stimulating hormone (FSH). FHS causes your ovaries to produce estrogen. When your ovaries slow down their production of estrogen, your levels of FSH increase. When FSH levels rise above 30 or 40 mIU/mL, it usually indicates that you are in menopause.

Summary: When we hear the word menopause, we usually think of ourselves. However, menopause is not a stage necessarily relegated to elderly women. Early menopause symptoms are more common than most women realize - it affects about 1% of women between the ages of 15 and 45. Early menopause symptoms can occur for a variety of reasons, but in the end it leaves an imprint on the lives of all of the women it affects.

Foods That Speed Metabolism

Copyright (c) 2008 Jason Szova

Do you want to speed up your metabolism and lose some body fat? Here are 14 foods that you can eat that will help you do just that.

Of course, you will always lose more weight if you follow a balanced nutrition plan and regular work out routine. These foods that speed metabolism, burn excess fat, and turn it into energy that we can all use.

14 Foods that Speed Metabolism:

1. Coffee:

Coffee beans have been around for thousands of years. Before coffee became a popular drink, sheepherders noticed when their sheep ate the beans the animals became more productive.

Ground coffee has been used as beverage for over seven hundred years. The caffeine in coffee causes our metabolism to speed up.

2. Water: Water is essential to almost every metabolic process in your body. Inadequate amounts of water leads to your body's metabolism not performing at its maximum.

Filling up with water can suppress hunger. Although you would think this would cause water weight gain- it is actually the opposite. The more water you drink, the less you retain.

3. Rolled Oats:

Rolled oats are usually sold as oatmeal, and the main ingredient in granola and muesli.

Eating complex carbohydrates and fiber, found in rolled oats products, keep insulin levels low. Insulin sends messages to the body that it should store fat.

Keeping insulin levels low allows your metabolism to burn excess fat.

4. Whey Protein:

Whey protein is a pure, natural, high quality protein from cow's milk. It is a rich source of the essential amino acids needed on a daily basis by the body.

In its purest form, it contains little or no fat, lactose, or cholesterol. Whey protein provides a healthy benefit in weight management.

5. Almonds: Almonds are the perfect snack. Nuts are high in metabolism-boosting protein and healthy fats.

6. Green Tea:

Green tea helps your body use more fat for energy. Drinking the tea provides weight loss benefits, along with anti-cancer and heart disease prevention.

Green tea leaves are packed with the chemical EGCG. New information suggests that catechin, the active ingredient in green tea, speeds up metabolism.

Research suggests that catechins improve thermogeneis, the body's production of energy from the digestive process.

7. Turkey: Turkey is a low fat, high protein food that can be readily used by your body to create more muscle.

Protein burns more calories than carbohydrates.

8. Extra Virgin Olive Oil: Olive oil is one of the healthiest cooking oils.

The oil is low in calories and polysaturated fat, but very high in monounsaturated fat, which benefits your body.

Extra virgin olive oil is a step above "virgin olive oil." Created without the use of any chemicals, the acidity of extra virgin oil is very low, and contains no cholesterol.

9. Canola Oil: The use of healthy cooking oils helps you lose weight, and fight the aging process. Canola oil contains monounsaturated fat, which is called the "healthy heart fat."

Canola oil is low in saturated fat, considered "bad" fat, and rich in Omega-3 fatty acids, a key component of heart health.

10. Whole grains:

Complex carbs such as whole grains, and whole grain cereal have a metabolism boosting effect.

Fiber slows down the digestive process, which speeds your metabolism.

11. Berries:

Berries contain antioxidants that speed up metabolism, burn off fat, and provide energy. Raspberries speed up metabolism by tripling the normal level in your body. The brindleberry is known as an appetite suppressant.

13. Cayenne Pepper:

Capsaicin is a chemical found in cayenne peppers that causes the human body to release stress hormones and boost metabolism.

This action stimulates the body to produce more adrenaline. That causes your metabolism to work overtime and aids in burning calories.

14. Vegetables: 'Good' carbohydrates are found in vegetables. Choose vegetables such as broccoli, which is loaded with fiber. Foods high in fiber content speed metabolism.

All of the above 14 foods that speed metabolism are known for their ability to break up stored body fat. A diet including these foods will increase your energy level to help you lose weight.
