Hashimoto's disease is a condition where your body's immune system mistakenly attacks your thyroid gland. This butterfly-shaped gland sits in your neck, just below your Adam's apple, and makes hormones that control many important bodily functions, like your metabolism and energy levels.
Normally, your immune system fights off germs and infections. But in Hashimoto's, it acts like it's attacking a foreign invader – your own thyroid cells. This attack gradually damages the cells that produce hormones. As a result, your body produces less of these crucial hormones (a condition called hypothyroidism).
While anyone can get Hashimoto's, it's more common in middle-aged women. It's important to note that the damage happens slowly, often over many years. Symptoms might not show up right away, or may be mild at first.
The main treatment for Hashimoto's is replacing the missing thyroid hormones. This involves taking a daily medication that provides the hormones your body isn't making. This medication helps to restore normal hormone levels and manage symptoms.
Hashimoto's disease is sometimes called Hashimoto's thyroiditis, chronic lymphocytic thyroiditis, or chronic autoimmune thyroiditis. These are just different names for the same condition.
Hashimoto's disease develops gradually over time. Often, people don't notice any early symptoms. As the thyroid gland produces less thyroid hormone, a number of changes can occur. These can include:
It's important to remember that not everyone with Hashimoto's will experience all of these symptoms, and the severity can vary greatly. If you have concerns about these symptoms, it's important to talk to a doctor.
Hashimoto's disease can cause a range of symptoms, and these symptoms aren't unique to this condition. Many other health problems can produce similar signs. For example, you might feel tired, have a swollen neck, or experience other symptoms. Because these symptoms could be linked to other issues, it's crucial to see a doctor as soon as possible for a proper diagnosis. Early diagnosis allows for the best treatment plan.
Hashimoto's disease happens when your body's immune system, which is supposed to fight off infections, mistakenly attacks your thyroid gland. Imagine your immune system is a trained army, and instead of attacking enemies like bacteria or viruses, it mistakenly attacks your own thyroid cells, treating them like invaders. These "disease-fighting" cells, called antibodies, damage the thyroid cells, eventually causing them to die.
Scientists don't fully understand why this happens. However, several things might play a role:
Hashimoto's disease is more common in certain people. Several factors increase the chances of developing this condition.
Gender: Women are significantly more likely to develop Hashimoto's disease than men.
Age: While Hashimoto's can happen at any age, it's more frequently diagnosed in middle-aged adults.
Existing Autoimmune Conditions: If you have another autoimmune disorder, like rheumatoid arthritis, type 1 diabetes, or lupus, you have a higher risk of developing Hashimoto's. Autoimmune disorders are conditions where your immune system mistakenly attacks healthy parts of your body. This increased risk suggests a link between the immune system's tendency to malfunction in one area and its potential to malfunction in another.
Family History: A family history of thyroid problems or other autoimmune diseases is a significant risk factor. If someone in your family has Hashimoto's, or other related illnesses, you might be more susceptible. This suggests a genetic component to the disease.
Pregnancy: Changes in the immune system during pregnancy can sometimes trigger or worsen Hashimoto's disease in some individuals. These changes can sometimes lead to the disease showing up after pregnancy.
Iodine Intake: While iodine is essential for thyroid health, consuming excessive amounts might trigger Hashimoto's in people already at risk. This suggests that a delicate balance is needed in iodine consumption.
Radiation Exposure: Exposure to high levels of radiation from the environment can increase the risk of Hashimoto's disease. This is likely because radiation can damage cells and potentially disrupt the delicate balance of the immune system.
Untreated thyroid problems, like Hashimoto's disease and hypothyroidism, can lead to various health issues. These conditions affect how your thyroid gland works, which is crucial for many bodily functions. Here's how:
Swollen Thyroid (Goiter): When your thyroid isn't making enough hormones, as in Hashimoto's disease, your pituitary gland (another gland in your brain) tells your thyroid to produce more. This extra effort can cause the thyroid gland to swell, forming a goiter. Most goiters aren't painful, but a large one can make it hard to swallow or breathe, and it might affect your appearance.
Heart Issues: Hypothyroidism can weaken your heart, making it work harder. This can lead to an enlarged heart, irregular heartbeats, and high levels of LDL cholesterol (the bad kind). High LDL cholesterol is a major risk factor for heart disease and heart failure.
Mental Health Problems: Hashimoto's disease and hypothyroidism can sometimes cause or worsen mental health issues, like depression. These problems can start early and get worse over time if not managed.
Sexual and Reproductive Problems: Women with hypothyroidism might experience a decreased sex drive (libido), irregular periods, heavy bleeding, and trouble getting pregnant. Men with hypothyroidism may experience a lower sex drive, difficulty getting an erection, and a lower sperm count.
Pregnancy Complications: If a woman has untreated hypothyroidism during pregnancy, it can increase the risk of miscarriage or giving birth prematurely. Babies born to mothers with untreated hypothyroidism may have problems with development, including learning disabilities, autism, speech delays, and other developmental issues.
Myxedema (a severe complication): If hypothyroidism is very severe and untreated for a long time, a rare but serious condition called myxedema can develop. This is a medical emergency. Myxedema involves swelling and fluid retention in the body. Symptoms include extreme tiredness and drowsiness, possibly progressing to unconsciousness. Cold temperatures, medications like sedatives, infections, or other stresses on the body can trigger myxedema, requiring immediate medical attention.
Hashimoto's disease can cause a range of symptoms. If you're experiencing these symptoms, your doctor will do a physical exam, review your medical history, and ask you about your symptoms.
To figure out if your symptoms are due to an underactive thyroid (hypothyroidism), your doctor will likely order blood tests. Several things can cause an underactive thyroid, but one common cause is Hashimoto's disease. To pinpoint if Hashimoto's is the issue, your doctor will order a specific blood test.
These tests look for antibodies. Antibodies are part of your immune system's defense. Normally, antibodies help fight off infections by attacking harmful invaders. But in autoimmune diseases like Hashimoto's, the immune system mistakenly attacks healthy parts of your body.
In Hashimoto's disease, the immune system often produces antibodies that target a protein called thyroid peroxidase (TPO). This protein is crucial for making thyroid hormones. If you have Hashimoto's, you're likely to have TPO antibodies in your blood. Your doctor might also test for other antibodies related to Hashimoto's.
Here are some key blood tests involved:
TSH Test: Your pituitary gland makes a hormone called thyroid-stimulating hormone (TSH). When your thyroid isn't making enough hormones, your pituitary gland releases more TSH to try and stimulate the thyroid. A high TSH level in your blood often suggests an underactive thyroid.
T4 Test: Thyroxine (T4) is the main thyroid hormone. A low level of T4 in your blood confirms the findings of the TSH test and shows the problem is specifically with your thyroid gland's ability to make enough hormone.
Treating Hypothyroidism with Levothyroxine (and Other Options)
Hashimoto's disease often leads to hypothyroidism, a condition where your thyroid gland doesn't produce enough hormones. This usually requires medication to replace the missing hormones.
How Levothyroxine Works
The most common treatment for hypothyroidism is levothyroxine, a synthetic version of the thyroid hormone T4. Your body naturally makes T4, and this synthetic version acts in a similar way. The goal of treatment is to get your T4 levels back to a healthy range and relieve hypothyroidism symptoms. You'll likely need to take levothyroxine for the rest of your life.
Getting the Right Dosage
Your doctor will determine the right dose of levothyroxine based on several factors, including your age, weight, how well your body is currently making thyroid hormone, and any other medical conditions you have. They'll check your thyroid-stimulating hormone (TSH) levels about two to three months after starting the medication to see if the dose needs adjusting. This process is repeated until your TSH levels are in the normal range.
Once your dosage is correct, you'll usually take it once a day, typically in the morning before eating. It's important to follow your doctor's instructions carefully. If you miss a dose, or if your insurance requires a generic or different brand, talk to your doctor.
Potential Side Effects and Interactions
Levothyroxine is generally safe and well-tolerated. However, taking too much can lead to problems like weakened bones (osteoporosis) or a rapid heartbeat.
Certain things can interfere with how well your body absorbs levothyroxine, including:
If you're taking any of these, your doctor might recommend taking levothyroxine at least four hours before or after them to ensure it's absorbed properly.
Other Thyroid Hormone Options
While levothyroxine is the most common treatment, your doctor might also prescribe a synthetic version of T3 (triiodothyronine) called Cytomel, or a combination of synthetic T3 and T4. This is often considered if you need better symptom control. These options have potential side effects like faster heart rate, sleep problems, and anxiety, and are often tested for a short period (3-6 months).
Important Note: Always discuss any questions or concerns you have about your treatment with your doctor. They can provide personalized advice based on your specific situation.
To figure out what's causing your hormone problems, you'll likely first visit your general doctor. They might then suggest seeing a specialist who deals with hormone issues, called an endocrinologist.
