Is it just midlife, or is your thyroid slowing down?


Maybe you're feeling tired and having trouble concentrating — or perhaps you've noticed changes in your hair or weight, or just feel blah. You might easily attribute these issues to other health problems, or to simply getting older. But these symptoms can be signs of a sluggish thyroid.
The thyroid is a butterfly-shaped gland in the neck. It produces the hormones that regulate metabolism. Low levels of thyroid hormone can cause a range of symptoms, including fatigue, constipation, dry skin, brittle nails, hair changes, aches and pains, and feeling down. Untreated, an underactive thyroid (hypothyroidism) can increase the chances of developing high cholesterol, high blood pressure, and heart disease.

Women are more likely than men to have problems with their thyroid, particularly as they get older. In some women, the onset of thyroid trouble is so gradual that it's hardly noticeable; in others, symptoms come on abruptly over the course of a few weeks or months. These include:
  • Fatigue. You may feel unusually tired and have less energy.
  • Cold intolerance. You may feel chilly even when others around you are comfortable.
  • Appetite loss, weight gain. When metabolism is dragging, you need fewer calories so your appetite may decrease — at the same time, you are using fewer of the calories you do eat, so more are stored as fat.
  • Cardiovascular effects. Low levels of thyroid hormone can lead to high blood pressure as well as elevated levels of total and LDL cholesterol. Over time, an underactive thyroid can compromise the ability of the heart to pump blood effectively.
  • Mental effects. Hypothyroidism and depression share many of the same symptoms, including trouble concentrating, memory problems, and loss of interest in things that are normally important to you.
  • Other signs and symptoms. Hypothyroidism can cause symptoms throughout the body, from constipation to muscle aches and pain around the joints. Skin, hair, and nails may become dry and thin.
If you have any of these symptoms, see your doctor. She or he will examine you for signs of hypothyroidism, and may recommend blood tests to check thyroid function.
Hypothyroidism is usually treated with a daily dose of synthetic thyroid hormone, which is taken as a pill. This medication works exactly like your body's natural thyroid hormone. It may take some time to find the right dose for you. Once you do, symptoms usually improve dramatically. Your doctor will check your thyroid function usually once or twice a year to be sure that your dose of medication remains optimal.

Women and sleep: 5 simple steps to a better night's rest

Sleep shortfalls can lead to a range of health problems, from being more likely to catch a cold or gain weight to increased risk of developing heart disease or diabetes.
For optimum health and function, the average adult should get seven to nine hours of sleep every night. But more than 60% of women regularly fall short of that goal.
This may be due to insomnia or another underlying condition that may require medical attention. But most women with a sleep debt run it up by burning the candle at both ends — consistently failing to get to bed on time or stay there long enough.
Don't worry about repaying the old sleep debt. Just make sure you start getting enough sleep from this point forward — starting tonight. Getting enough sleep is just as important as eating a healthy diet and getting regular exercise.
Tips for getting the rest you need:
  1. Create a sleep sanctuary. Reserve your bedroom for sleep and intimacy. Keep it on the cool side. Banish the television, computer, smartphone or tablet, and other diversions from that space.
  2. Nap only if necessary. Taking a nap at the peak of sleepiness in the afternoon can help to supplement hours missed at night. But naps can also interfere with your ability to sleep at night and throw your sleep schedule into disarray. If you need to nap, limit it to 20 to 30 minutes.
  3. Avoid caffeine after noon, and go light on alcohol. Caffeine can stay in your body for up to 12 hours. Alcohol can act as a sedative, but it also disturbs sleep.
  4. Get regular exercise, but not within three hours of bedtime. Exercise acts as a short-term stimulant.
  5. Avoid backsliding into a new debt cycle. Try to go to bed and get up at the same time every day — at the very least, on weekdays. If need be, use weekends to make up for lost sleep.
