Why are so many people on Synthroid?

Many people are on Synthroid (levothyroxine) because it's the primary treatment for hypothyroidism (underactive thyroid), a common condition where the thyroid doesn't make enough hormones, impacting energy and organ function, but there's also concern about overuse for mild cases or non-thyroid issues, with some studies suggesting millions might be on it unnecessarily. Factors like aging, pregnancy, menopause, and autoimmune diseases contribute to its high prescription rate, but research shows some patients, especially older adults, might not benefit from treatment for mild thyroid issues.

Why do so many people have thyroid problems now?

The reason is not clear, but some researchers suspect it may be due to an increase in iodine deficiency during these years. Gender: While men and women have an equal chance of developing Graves' disease and Hashimoto's disease, women are more likely than men to have hypothyroidism.

What are the problems with Synthroid?

Taking too much or too little SYNTHROID may lead to negative effects on growth and development, heart function, bone health, reproductive function, mental health, digestive function, and changes in blood sugar and cholesterol metabolism in adult or pediatric patients.

Is hypothyroidism overdiagnosed?

Subclinical hypothyroidism may be overdiagnosed due to reference ranges not adjusted for factors such as race, sex, and age, according to new data.

What is the most prescribed thyroid medication?

The most common thyroid treatment is synthetic T4 hormone medication, usually prescribed as the drug Synthroid® or Levoxyl®. In fact, Synthroid® is the most commonly prescribed drug in America, with 21.6 million prescriptions a month.

SURPRISING Side Effects of Levothyroxine (No one talks about these)

Why is Synthroid so common?

There is also a link between hypothyroidism and certain thyroid cancers. This may in part explain why providers write so many prescriptions for Synthroid and its generic equivalents each year.

What is the downside to taking levothyroxine?

The greatest risks of long-term treatment with levothyroxine are: An increased risk of heart disease, especially in older adults and people with pre-existing heart conditions. An increased risk of osteoporosis and bone fractures, especially in post-menopausal women and elderly patients above 70 years of age.

What is the life expectancy of a person with hypothyroidism?

With proper, consistent treatment using thyroid hormone replacement, hypothyroidism generally does not significantly impact life expectancy, allowing individuals to live a normal, healthy life; however, untreated or poorly managed hypothyroidism can increase risks for serious issues like heart disease, impacting longevity. While some studies show subtle links between low-normal thyroid function and longer life, the key takeaway is that effective treatment normalizes health and lifespan. 

What can worsen hypothyroidism?

Hypothyroidism gets worse with things that disrupt hormone levels or absorption, like too much iodine, certain supplements (calcium, iron), foods (soy, excessive goitrogens, processed foods), stress, alcohol, and taking thyroid meds with caffeine, while factors like genetics, inflammation, and autoimmune issues (Hashimoto's) also play a big role in symptom flares. Not taking medication correctly or in the right dose also worsens symptoms.
 

What does overmedicated thyroid feel like?

Too much thyroid medication in hypothyroidism can cause health problems and trigger symptoms like the jitters, anxiety, weight loss, diarrhea and mood swings. Your thyroid hormone needs may change over time.

Which is safer, Synthroid or levothyroxine?

Levothyroxine is a generic version of brand-name Synthroid. A generic drug is an exact copy of the active drug in a brand-name medication. In general, generics are considered to be as effective and safe as the brand-name drug.

Can Synthroid cause mental issues?

Levothyroxine (Synthroid) is a common treatment for hypothyroidism, but if your dose is too high, it can directly lead to anxiety and cause symptoms like rapid heartbeat and shakiness, which can make anxiety worse, says Dr. Rosenfeld.

What is the average age for thyroid problems?

Thyroid problems are most common in women, especially over age 60, with hypothyroidism (underactive thyroid) steadily increasing with age, affecting up to 15% of those over 70. While hypothyroidism is common in older adults, hyperthyroidism (overactive thyroid) also occurs, particularly in those over 60. Specific conditions like Hashimoto's thyroiditis often begin between 30-50, and Graves' disease typically affects people between 30-60.
 

How to cure hypothyroidism permanently?

Taken daily, levothyroxine can even out your hormone levels and eliminate your symptoms. It'll take a bit of trial and error to find the right dosage. To do this, your provider will run routine thyroid blood tests until your TSH levels even out. You'll need to take hypothyroidism medication for the rest of your life.

What is the root cause of hypothyroidism?

The root cause of hypothyroidism (underactive thyroid) is most often the immune system attacking the thyroid (Hashimoto's disease) in iodine-sufficient areas, or severe iodine deficiency globally, leading to inflammation and insufficient hormone production. Other common causes include thyroid surgery, radiation treatment, certain medications, pituitary gland issues, and genetic defects, while stress and nutrient deficiencies (like Vitamin D, Selenium) can also play a role in its development or worsening.
 

What vitamins should you avoid with hypothyroidism?

With hypothyroidism, you should avoid excess iodine, as it can worsen symptoms, and be cautious with calcium & iron supplements (including some multivitamins) because they block thyroid medication absorption; take them hours apart from your levothyroxine. Also, be wary of high selenium (can be toxic), biotin (interferes with tests), and some herbs like kelp, always checking with your doctor before starting anything new.
 

What is stage 5 hypothyroidism?

Stage 5: Full-blown Hashimoto's/hypothyroidism

Typically, the TSH level will become elevated or high-normal, and Free T4 and Free T3 levels are at the low end of the range or below normal.

Which fruit is not good for the thyroid?

Fruits like strawberries, peaches, and pears contain goitrogens that might interfere with iodine uptake, especially in large amounts or if iodine deficient, while fruits with high sugar (like overripe bananas) or high oxalate (prunes) could indirectly worsen symptoms by causing inflammation or interfering with mineral absorption, but moderation is key, and cooking reduces goitrogens. The main concern for thyroid health usually involves excessive intake or pre-existing deficiencies, not normal fruit consumption. 

What emotions are held in the thyroid?

In relation to thyroid hormones, triiodothyronine (T3) is known to control the levels and activities of serotonin and noradrenaline [60]. Depression and anxiety disorders can be brought on by low T3, and these illnesses are also associated with low serotonin and noradrenaline levels.

What is the long-term damage of levothyroxine?

Long-term levothyroxine use is generally safe and effective for hypothyroidism but carries risks, primarily from overdosing, which can lead to osteoporosis (bone loss) and heart problems (like arrhythmias or heart failure). While some studies suggest potential links to increased cancer risk, these findings need confirmation, but proper dosing via regular blood tests is crucial to prevent serious side effects and maintain bone/heart health.
 

Is there a safer alternative to levothyroxine?

Natural desiccated thyroid extract (DTE)

They are sold under various brand names, such as NP Thyroid, Nature-Throid, Armour Thyroid, and others. Some people find that taking Armour Thyroid or other natural options is a better levothyroxine alternative, perhaps because these natural alternatives contain both T4 and T3.

What not to do when taking levothyroxine?

Is there any food or drink I need to avoid? There are some foods and drinks that do not mix well with levothyroxine: drinks containing caffeine, like coffee, tea and some fizzy drinks, can reduce the amount of levothyroxine your body takes in. Leave at least 30 minutes after taking levothyroxine before you drink them.
