What is hypothyroidism?
Hypothyroidism means the thyroid gland is not making enough thyroid hormone to keep the body running at a normal pace. It is common, especially as people get older and in those with a family history of thyroid disease. The most common cause is Hashimoto's thyroiditis, an autoimmune condition in which the body's own immune system gradually slows the thyroid. Typical symptoms include fatigue, weight gain, feeling cold, dry skin, constipation, and brain fog or low mood. Because these symptoms are nonspecific, the diagnosis is confirmed with a blood test — usually TSH, sometimes with Free T4. Once diagnosed, hypothyroidism is very treatable with a daily thyroid hormone tablet, and most people feel substantially better once their levels are in range.
How online thyroid care works
You complete a secure online intake describing your diagnosis, current medication and dose, most recent labs, symptoms, interacting medications, and pharmacy preference. A licensed physician reviews the information and may follow up if more detail is needed. If you have established, stable hypothyroidism with recent labs, the clinician can send a levothyroxine prescription to your pharmacy. If your labs are not current, Start & Confirm includes a TSH so the clinician can review your levels before prescribing.
Vyta.co manages straightforward hypothyroidism — it does not work up complex or undifferentiated thyroid disease. If your answers suggest hyperthyroidism, a nodule or mass, thyroid cancer, pregnancy, or any picture that needs specialist-level care, the clinician will refer you for in-person evaluation at no charge.

When online thyroid care is appropriate
Telehealth may be appropriate for adults with established, stable hypothyroidism who need ongoing levothyroxine refills and routine monitoring — or for symptomatic adults whose labs confirm straightforward, uncomplicated hypothyroidism.
Because thyroid symptoms overlap with other conditions and only labs confirm the diagnosis, your clinician reviews your history and TSH before deciding whether treatment is clinically appropriate.
When to see a doctor in person
Online management is not right for every thyroid situation. Seek in-person care if any of the following apply.
- Pregnancy, or planning pregnancy within the next six months
- A history of thyroid cancer, or thyroid nodules or masses
- Hyperthyroidism or Graves' disease, or symptoms of an overactive thyroid (racing heart, tremor, unexplained weight loss)
Levothyroxine: how treatment works
Levothyroxine is a synthetic form of the thyroid hormone T4 and is the standard first-line treatment for hypothyroidism. It is taken once daily, ideally on an empty stomach 30 to 60 minutes before breakfast, because food and certain supplements affect absorption. Calcium, iron, antacids, and proton-pump inhibitors (PPIs) should be separated from your dose by several hours. The clinician starts conservatively and adjusts based on your symptoms and labs, rechecking your TSH about 6 to 8 weeks after any dose change.
Take levothyroxine consistently and tell your clinician about new medications or supplements, since they can change how much you absorb. If you have symptoms of too much thyroid hormone — a racing heart, tremor, trouble sleeping, or unexplained weight loss — let your clinician know, as your dose may need to come down. Your clinician chooses the dose and monitoring plan based on your individual situation.
What causes hypothyroidism?
The most common cause is Hashimoto's thyroiditis, an autoimmune condition. Other causes include prior thyroid surgery, radioactive iodine treatment, certain medications, and, less commonly, problems with the pituitary gland. Risk is higher with a family history of thyroid or autoimmune disease and with older age. Hypothyroidism is usually a lifelong condition, which is why steady refills and periodic monitoring matter more than a one-time fix.
Labs & monitoring
TSH is the main test used to diagnose hypothyroidism and to guide dosing, sometimes alongside Free T4. Once your dose is stable, most adults need a TSH check about once a year — the American Thyroid Association suggests every 6 to 12 months once stable. After any dose change, your clinician rechecks sooner, usually in 6 to 8 weeks. The membership includes one monitoring TSH per year; any additional labs are billed at cost.
Why this matters in Texas
Texas is the second most populous state in the country and covers 254 counties, more than any other state (US Census QuickFacts). Hypothyroidism is common and lifelong, and for a stable patient the work is mostly refills and an annual TSH check. That is routine care that does not require sitting in a waiting room, which is exactly what online management is built for.
Access is the harder problem here. Endocrinology in Texas clusters in Houston, Dallas-Fort Worth, San Antonio, and Austin. Across much of West Texas, the Panhandle, and the Rio Grande Valley, the nearest specialist can be a multi-hour drive, and a routine follow-up slot can be months out. A levothyroxine prescription that lapses because the appointment was too far away is a common and avoidable problem.
Cost is the other half of the story. Texas has the highest uninsured rate in the country, and for someone paying cash a specialist visit to confirm a stable thyroid dose is hard to justify, so refills get stretched or skipped. Online care puts a flat price on the routine part: a Texas-licensed physician reviews your history and recent labs, confirms your dose, and keeps your levothyroxine coming without an appointment.
Is online thyroid care legal in Texas?
Yes. Telemedicine in Texas is governed by Texas Occupations Code Chapter 111, which lets a Texas-licensed clinician establish a practitioner-patient relationship and deliver telemedicine medical services, subject to the same standard of care that applies in person. Non-controlled medications may be prescribed that way, and levothyroxine is not a controlled substance. Controlled substances are never prescribed online. Your Texas-licensed clinician reviews your thyroid history and labs and may ask for more information before deciding whether treatment is appropriate.
