What is Hyperthyroidism?
A disorder of an overactive thyroid gland. This causes overactivity of thyroid hormones that are needed for growth, development, and metabolism. Causes include viral infections, brain disorders, and autoimmunity (where the body's immune system attacks itself). Symptoms include weight loss, tremors and palpitations and/or rapid heart rate.
Typical Symptoms of Hyperthyroidism
- Enlarged male breast tissue
- Eye are bulging or jutting out
- Feeling unusually energetic
- Wheezing or whistling sounds when breathing
- Pounding, rapid or fluttering heartbeat during exercise
- Black/blue/brown spots or moles, on the skin and lining of the mouth
- Fine tremors of the hands or fingers
- Feels a hard lump in upper right abdomen
Diagnostic Questions for Hyperthyroidism
Your doctor may ask these questions to check for this disease:
- Have you noticed an unusual increase in your breast size?
- Do your eyes bulge?
- Have you been feeling unusually energetic lately?
- Do you experience wheezing or whistling sounds when breathing?
- Do you get heart palpitations when you exercise?
Treatment of Hyperthyroidism
The treatment aims to stop the thyroid from overproducing hormones. Options include anti-thyroid medications, radioactive iodine therapy, and surgery to remove the thyroid. At the same time, medications may be prescribed to control symptoms like palpitations and anxiety.

User Testimonials for Hyperthyroidism
Male, 30s
I was really impressed with Ubie Health's symptom checker. It covered all my symptoms including fatigue, depression, and excessive drooling which is not something I have seen on other platforms. The results pointed me toward possible hyperthyroidism, so I scheduled an appointment with my doctor to figure out the best course of action. Its a great tool for getting quick results so I can have more of an idea of what's going on with me health-wise. I also liked how it showed me that I wasn't alone! It said there were 168 other people who had symptoms just like me in the past six months, so I didn't feel weird or embarrassed about my symptoms anymore. I highly recommend this site.

Q.
Racing Heart? Why Your Thyroid Is Overactive & Medically Approved Next Steps
A.
A racing or pounding heartbeat can be caused by hyperthyroidism, when excess thyroid hormone speeds your heart and metabolism, often with palpitations, weight loss, heat intolerance, tremor, and anxiety. There are several factors to consider; medically approved next steps include urgent care for red flags like chest pain or fainting, thyroid blood tests to confirm the diagnosis, and treatments like beta blockers, antithyroid drugs, radioactive iodine, or surgery depending on the cause. See the complete details below to understand what to do next and which options may fit your situation.

Q.
Heart Racing? Why Your Internal Engine Is Stuck in Overdrive: Hyperthyroidism & Medical Next Steps
A.
A racing or pounding heart with tremors, weight loss, anxiety, heat intolerance, or sleep trouble can point to hyperthyroidism, a treatable condition where excess thyroid hormone puts your body in overdrive; diagnosis is by blood tests and treatments include antithyroid medication, radioactive iodine, or surgery, with beta blockers for symptom relief. There are several factors to consider that affect urgency and next steps, including heart rhythm risks and when to seek emergency care for chest pain, severe shortness of breath, fainting, or confusion. See below for the complete answer with what to ask your doctor, which tests confirm the cause, and how each treatment’s pros and cons could change your plan.

Q.
Hyperthyroidism in Women 30-45: Symptoms & Your Action Plan
A.
Hyperthyroidism is common and treatable in women 30 to 45; key signs include unexplained weight loss, rapid or irregular heartbeat, anxiety, tremor, heat intolerance, and menstrual changes that can affect fertility. Diagnosis is straightforward with TSH and free T4/T3 blood tests, and treatments include antithyroid medications, radioactive iodine, or surgery depending on the cause. There are several factors to consider, including Graves disease as a common cause, risks to your heart and bones, pregnancy and postpartum planning, and a step by step action plan for tracking symptoms, getting labs, and knowing when to seek urgent care; see the complete guidance below.

Q.
High or Low THS Test Results? Here’s What They Mean
A.
High TSH usually signals an underactive thyroid and low TSH suggests an overactive thyroid. Doctors interpret results with your symptoms and other labs like Free T4 and T3 because the typical range of about 0.4 to 4.0 mIU/L can vary with age, pregnancy, medications, and health conditions. There are several factors to consider, including subclinical results that may only need monitoring, common causes and treatments, when to repeat testing, and urgent warning signs like chest pain, severe weakness, or a very fast or irregular heartbeat that need prompt care. See complete details below to guide your next steps and what to discuss with your clinician.

Q.
THS Test: What It Measures and Why Doctors Order It
A.
The TSH Thyroid Stimulating Hormone test measures the level of TSH in your blood to gauge thyroid function, with high TSH suggesting hypothyroidism and low TSH suggesting hyperthyroidism; doctors order it to investigate symptoms, screen at-risk people, and monitor treatment. Results are interpreted alongside your symptoms, history, and often free T4 or T3, and next steps may include repeating the test, additional labs, medication changes, or referral to an endocrinologist. There are several factors to consider for your situation, so see the complete details below to understand nuances that could affect your next steps.

Q.
What is drisdol and is it safe to use?
A.
Drisdol is a prescription form of vitamin D2 (ergocalciferol) used to treat and prevent vitamin D deficiency, supporting healthy bones, calcium balance, and muscle function. It is generally safe when used as directed with medical oversight, but there are several factors to consider because excessive dosing can cause high calcium, kidney problems, and other side effects or drug interactions. For important details that could change your next steps such as who should be cautious, monitoring needs, and when to seek help, see below.

Q.
What conditions make alkaline phosphatase low on lab tests?
A.
Low alkaline phosphatase can result from genetic hypophosphatasia; nutrient deficiencies (zinc, magnesium, protein); endocrine issues (hypothyroidism, poorly controlled diabetes); hematologic disorders (vitamin B12 deficiency, aplastic anemia); malabsorption (celiac/IBD); liver/metabolic disease (Wilson disease, severe fatty liver); severe illness or cachexia; medications/toxins (chemotherapy, corticosteroids, heavy metals); and even lab handling or assay errors. Mild reductions can be benign, but very low levels—especially with bone pain, fractures, jaundice, or persistent fatigue—warrant medical follow‑up; there are several factors to consider, and important testing and next steps are detailed below.
