Let us tell you Everything You Need to Know About Hypothyroidism.
Hypothyroidism happens when your body doesn’t produce enough thyroid hormones. The thyroid is a small, butterfly-shaped gland that sits at the front of your neck. It releases hormones to help your body regulate and use energy.
Your thyroid is responsible for producing energy for nearly every organ in your body. It regulates functions like how your heart beats and how your digestive system works. Without the right amount of thyroid hormones, your body’s natural functions begin to slow down.
Also called underactive thyroid, hypothyroidism affects women more regularly than men. It usually affects people over the age of 60 but can begin at any age. It may be discovered through a routine blood test or after symptoms begin.
The signs and symptoms of hypothyroidism
Early symptoms can include weight gain and fatigue. Both become more common as you age, regardless of your thyroid’s health. You may not realize that these changes are related to your thyroid until more symptoms appear.
For most people, symptoms of the condition improve gradually over many years. As the thyroid slows more and more, the symptoms may become more easily recognized. Of course, many of these symptoms also become more common with age in general. If you suspect your symptoms result from a thyroid problem, you must talk with your doctor. They can order a blood test to determine if you have hypothyroidism.
The most common signs and symptoms of hypothyroidism include:
- feeling cold
- dry skin
- weight gain
- muscle weakness
- decreased sweating
- slowed heart rate
- elevated blood cholesterol
- pain and stiffness in your joints
- dry, thinning hair
- impaired memory
- fertility difficulties or menstrual changes
- muscle stiffness, aches, and tenderness
- puffy, sensitive face
Common causes of hypothyroidism include:
An autoimmune disease
Your immune system is designed to protect your body’s cells against invading bacteria and viruses. When unknown bacteria or viruses enter your body, your immune system responds by sending out fighter cells to destroy the foreign cells.
Sometimes, your body confuses normal, healthy cells for invading cells. This is called an autoimmune response. If the autoimmune response isn’t regulated or treated, your immune system can attack healthy tissues. This can cause serious medical issues, including conditions like hypothyroidism.
Hashimoto’s thyroiditis is an autoimmune condition and the most common cause of an underactive thyroid. This disease attacks your thyroid gland and causes chronic thyroid inflammation. The inflammation can reduce thyroid function. It’s common to find multiple family members with this same condition.
Treatment for hyperthyroidism
If your thyroid gland produces too much thyroid hormone, you have a condition known as hyperthyroidism. Treatment for this condition aims to decrease and normalize thyroid hormone production. Sometimes, treatment can cause the levels of your thyroid hormone to remain low permanently. This often occurs after treatment with radioactive iodine.
Surgical removal of your thyroid
If your entire thyroid gland is removed due to thyroid problems, you’ll develop hypothyroidism. Using thyroid medication for the rest of your life is the primary treatment.
If only a part of the gland is removed, your thyroid may still be able to produce enough hormones on its own. Blood tests will help determine how much thyroid medication you’ll need.
If you’ve been diagnosed with cancer of the head or neck, lymphoma, or leukemia, you may have undergone radiation therapy. Radiation used for the treatment of these conditions may slow or halt the production of thyroid hormone. This will almost always lead to hypothyroidism.
Several medicines may lower thyroid hormone production. These include ones used to treat psychological conditions, as well as cancer and heart disease. This can lead to hypothyroidism.
Two primary tools are used to determine if you have hypothyroidism:
Your doctor will complete a thorough physical exam and medical history. They’ll check for physical signs of hypothyroidism, including:
- dry skin
- slowed reflexes
- a slower heart rate
In addition, your doctor will ask you to report any symptoms you’ve been experiencing, such as fatigue, depression, constipation, or feeling constantly cold.
If you have a known family history of thyroid conditions, you must tell your doctor during this exam.
Medications for hypothyroidism
Hypothyroidism is a lifelong condition. For many people, the medication reduces or alleviates symptoms.
Hypothyroidism is best treated by using levothyroxine (Levothroid, Levoxyl). This synthetic version of the T4 hormone copies the action of the thyroid hormone your body would normally produce.
The medication is designed to return adequate levels of thyroid hormone to your blood. Once hormone levels are restored, symptoms of the condition are likely to disappear or at least become much more manageable.
Once you start treatment, it takes several weeks before you begin feeling relief. You’ll require follow-up blood tests to monitor your progress. You and your doctor will work together to find a dose and a treatment plan that best addresses your symptoms. This can take some time.
In most cases, people with hypothyroidism must remain on this medication their entire lives. However, it’s unlikely you’ll continue to take the same dose. To make sure your medication is still working properly, your doctor should test your TSH levels yearly.
If blood levels indicate the medicine isn’t working as well as it should, your doctor will adjust the dose until a balance is achieved.
Alternative treatment for hypothyroidism
Animal extracts that contain thyroid hormones are available. These extracts come from the thyroid glands of pigs. They contain both T4 and triiodothyronine (T3).
If you take levothyroxine, you’re only receiving T4. But that’s all you need because your body is capable of producing T3 from the synthetic T4.
These alternative animal extracts are often unreliable in dosing and haven’t been shown in studies to be better than levothyroxine. For these reasons, they aren’t routinely recommended.
Additionally, you can purchase glandular extracts in some health food stores. These products aren’t monitored or regulated by the U.S. Food and Drug Administration. Because of this, their potency, legitimacy, and purity aren’t guaranteed. Use these products at your own risk. But do tell your doctor if you decide to try these products to adjust your treatment accordingly.
Dietary recommendations for people with hypothyroidism
As a general rule, people with hypothyroidism don’t have a specific diet they should follow. However, here are some recommendations to keep in mind:
Eat a balanced diet
Your thyroid needs adequate amounts of iodine to function fully. You don’t need to take an iodine supplement for that to happen. A balanced diet of whole grains, beans, lean proteins, and colorful fruits and vegetables should provide enough iodine.
Monitor soy intake
Soy may hinder the absorption of thyroid hormones. If you drink or eat too many soy products, you may not properly absorb your medication. This can be especially important in infants needing treatment for hypothyroidism who also drink soy formula.
Soy is found in:
- vegan cheese and meat products
- soy milk
- soy sauce
You need steady doses of the medication to achieve even levels of thyroid hormone in your blood. Avoid eating or drinking soy-based foods for at least two hours before and after you take your medication.
Be smart with fiber
Like soy, fiber may interfere with hormone absorption. Too much dietary fiber may prevent your body from getting the hormones it needs. Fiber is important, so don’t avoid it entirely. Instead, avoid taking your medicine within several hours of eating high-fiber foods.
Don’t take thyroid medicine with other supplements
If you take supplements or medications in addition to thyroid medicine, try to take these medicines at different times. Other medications can interfere with absorption, so it’s best to take your thyroid medicine on an empty stomach without other medicines or foods.
Living with hypothyroidism: Things to consider
Even if you’re undergoing treatment, you may deal with long-lasting issues or complications because of the condition. There are ways to lessen the effect of hypothyroidism on your quality of life:
Develop fatigue coping strategies
Despite taking medication, you may still experience fatigue from time to time. It’s important you get quality sleep each night, eat a diet rich in fruits and vegetables, and consider the use of stress-relieving mechanisms, like meditation and yoga, to help you combat low energy levels.
Talk it out
Having a chronic medical condition can be difficult, especially if other health concerns accompany it. Find people you can openly express your feelings and experiences to. This can be a therapist, close friend, family member, or a support group of other people living with this condition.
Many hospitals sponsor meetings for people with conditions like hypothyroidism. Ask for a recommendation from your hospital’s education office, and attend a meeting. You may be able to connect with people who understand exactly what you’re experiencing and can offer a guiding hand.
Monitor for other health conditions
There is a link between other autoimmune diseases and hypothyroidism.
Hypothyroidism often goes along with other conditions like:
- celiac disease
- rheumatoid arthritis
- adrenal gland disorders
- pituitary problems
- obstructive sleep apnea
Hypothyroidism and depression
When levels of thyroid hormones are low, your body’s natural functions slow down and lag. This creates a variety of symptoms, including fatigue, weight gain, even depression.
Some people with hypothyroidism may only experience mood difficulties. This can make diagnosing hypothyroidism difficult. Instead of only treating the brain, doctors should also consider testing for and treating an underactive thyroid.
Depression and hypothyroidism share several symptoms. These include:
- difficulty concentrating
- weight gain
- depressed mood
- reduced desire and satisfaction
- sleep difficulties
The two conditions also have symptoms that may distinguish them from one another. For hypothyroidism, problems such as dry skin, constipation, high cholesterol, and hair loss are common. For depression alone, these conditions wouldn’t be expected.
Depression is often a diagnosis made based on symptoms and medical history. Low thyroid function is diagnosed with a physical exam and blood tests. To see if there’s a link between your depression and your thyroid function, your doctor can order these tests for a definitive diagnosis.
If your depression is caused only by hypothyroidism, correcting the hypothyroidism should treat the depression. If it doesn’t, your doctor may prescribe medications for both conditions. They’ll slowly adjust your doses until your depression and hypothyroidism come under control.
Hypothyroidism and anxiety
While hypothyroidism has long been associated with depression, a recent study indicates it may be associated with anxiety, too. Researchers recently evaluated 100 patients between the ages of 18 and 45 with a known history of hypothyroidism. Using an anxiety questionnaire, they found that nearly 60 percent of people with hypothyroidism met the criteria for some form of anxiety.
The research to date has consisted of small studies. Larger and more focused studies on anxiety may help determine if a true connection exists between hypothyroidism and anxiety. You and your doctor need to discuss all your symptoms when being evaluated for thyroid conditions.
Hypothyroidism and pregnancy
Hypothyroidism affects your entire body. Your thyroid is responsible for many of your body’s daily functions, including metabolism, heartbeat, and temperature control. When your body doesn’t produce enough thyroid hormone, all of these functions can slow.
- low birth weight
- brain development problems
- congenital disabilities
Women with thyroid problems can and very often do have healthy pregnancies. If you have hypothyroidism and are pregnant, it’s important to keep the following in mind during the time you’re expecting:
Stay current on medicine.
Continue to take your medication as prescribed. It’s common to have frequent testing so your doctor can make any necessary adjustments to your thyroid medication as your pregnancy progresses.
Talk to your doctor about testing.
Women can develop hypothyroidism while they’re pregnant. This occurs in three to five out of every 1,000 pregnancies. Some doctors routinely check thyroid levels during pregnancy to monitor for low thyroid hormone levels. If the levels are lower than they should be, your doctor may suggest treatment.
Some women who never had thyroid problems before they were pregnant may develop them after having a baby. This is called postpartum thyroiditis. In about 80 percent of women, the condition resolves after a year, and medication is no longer required. Approximately 20 percent of women who have this diagnosis will go on to require long-term therapy.
Your body needs more nutrients, vitamins, and minerals while you’re pregnant. Eating a well-balanced diet and taking multivitamins while you’re pregnant can help maintain a healthy pregnancy.
Hypothyroidism and weight loss
Your thyroid gland creates hormones that are responsible for a large number of bodily functions. These functions include using energy, controlling body temperature, keeping organs functioning, and regulating metabolism.
When thyroid hormone levels are low, research shows that people are more likely to gain weight. That’s likely because their body doesn’t burn energy efficiently as a body with a healthier thyroid. The amount of weight gain isn’t very high, however. Most people will gain somewhere between 5 and 10 pounds.
Once you’re treated for this condition, you may lose any weight that you’ve gained. If treatment doesn’t help eliminate the extra weight, you should lose weight with a change in diet and an increase in exercise. That’s because once your thyroid levels are restored, your ability to manage your weight returns to normal.
Hypothyroidism and weight gain
When your thyroid doesn’t function as well as it should, many of your body’s functions slow down. This includes the rate at which you use energy or metabolic rate.
If your thyroid gland doesn’t function properly, your resting or basal metabolic rate may be low. For that reason, an underactive thyroid is commonly associated with weight gain. The more severe the condition is, the greater your weight gain is likely to be.
Properly treating the condition can help you lose any weight you gained while your thyroid levels were uncontrolled. However, it’s important to know that’s not always the case. Symptoms of an underactive thyroid, including weight gain, develop over a long period of time.
It’s not uncommon for people with low thyroid hormones to lose weight once they find treatment for the condition. That doesn’t mean the condition isn’t being properly treated. Instead, the weight gain may be the result of lifestyle rather than low hormone levels.
If you’ve been diagnosed with hypothyroidism and are treating the condition but don’t see a change in your weight, you can still lose weight. Work with your doctor, registered dietitian, or personal trainer to develop a focused, healthy eating plan and exercise strategy that can help you lose weight.
Facts and statistics about hypothyroidism
The disease gets more common with age. People over age 60 experience it more frequently.
Women are more likely to have an underactive thyroid. In fact, 1 in 5 women will develop hypothyroidism by age 60.
One of the most common causes of an underactive thyroid gland is Hashimoto’s thyroiditis. It affects middle-aged women most commonly, but it can occur in men and children. This condition also runs in families. If a family member has been diagnosed with this disease, your risk for having it is higher.
It’s important to pay attention to changes your body goes through during your life span. If you notice a significant difference in how you feel or how your body responds, talk to your doctor to see if a thyroid problem may affect you.
