If your energy is crashing, your hairbrush is full, or your heart feels like it’s sprinting while you’re sitting still, your thyroid could be part of the story. Thyroid hormones set your body’s “idle speed.” Too little hormone, and everything slows. Too much, and everything races. In clinic, we listen to your timeline, look closely at subtle physical clues, and back it up with targeted labs. The goal is simple, science-backed clarity so you know what is happening and how to fix it.
Hypothyroid vs Hyperthyroid, what to know
Hypothyroidism, underactive thyroid
-
Energy: low, heavy fatigue that sleep does not fix
-
Bowels: constipation or “sluggish” gut
-
Weight: gradual gain or difficulty losing despite effort
-
Skin and hair: dry skin, coarse or thinning hair, hair shedding
-
Temperature: cold intolerance, cold hands and feet
-
Mood and brain: low mood, brain fog, slowed thinking
-
Heart: slower pulse, sometimes fluid retention
Hyperthyroidism, overactive thyroid
-
Energy: wired but tired, jittery
-
Bowels: frequent stools or diarrhea
-
Weight: unintentional loss or difficulty maintaining weight
-
Skin and hair: warm, moist skin, fine hair, shedding
-
Temperature: heat intolerance, sweating
-
Mood and brain: anxiety, irritability, sleep trouble
-
Heart: fast or irregular heartbeat, palpitations
You might have a mix of symptoms. That is common during transitions or thyroiditis. Patterns plus labs tell the real story.
Why your endocrinologist looks at your hands
Hands are a quick window into thyroid status. We check for:
-
Temperature and moisture. Cold, dry hands fit hypothyroidism. Warm, damp palms fit hyperthyroidism.
-
Tremor. A fine, high frequency tremor with arms outstretched can point to hyperthyroidism.
-
Nails and skin. Ridged or brittle nails, slow nail growth, dry or rough knuckles suggest low thyroid. Soft nails that peel, fast growth, or warm, flushed skin can suggest high thyroid.
-
Reflexes. We tap reflexes gently. In hypothyroidism, relaxation after the tap can be delayed. In hyperthyroidism, reflexes can be brisk.
-
Swelling. Puffy fingers or carpal tunnel symptoms can accompany hypothyroidism.
This quick exam adds context to your symptoms and labs. It helps us spot outliers early and personalize your treatment.
Symptoms to never ignore
Call your clinician promptly if you have:
-
Chest pain, shortness of breath, or fainting
-
Resting heart rate persistently over 100, new irregular heartbeat, or pounding palpitations
-
Severe weakness, confusion, or fever with neck pain and a very tender thyroid
-
Rapidly enlarging neck mass or new hoarseness
-
Postpartum red flags, severe anxiety, racing heart, or profound fatigue in the months after delivery
Most thyroid symptoms are manageable and not emergencies, but these deserve urgent attention.
Our testing approach, simple and targeted
We start with the right labs, not all the labs.
-
TSH, the pituitary signal that responds to thyroid levels
-
Free T4 and sometimes Free T3, the active hormones your tissues use
-
Thyroid antibodies when indicated, TPO and sometimes Tg antibodies when autoimmune thyroid disease such as Hashimoto’s is suspected; TRAb/TSI when hyperthyroidism could be autoimmune Graves disease
If you have a nodule, neck fullness, or prior imaging, we discuss targeted ultrasound. At Sol Endocrinology, we provide in-office thyroid ultrasound, and when needed, quick, ultrasound-guided biopsy with board-certified thyroid pathology review. This keeps your care moving without extra facility hops.
How dosing is adjusted over time
If you have hypothyroidism, we replace what your body needs. Levothyroxine is the usual starting point. Some patients benefit from combination therapy after a careful discussion.
-
Start low, go steady. We begin with a dose based on age, weight, cardiac history, and symptom profile.
-
Recheck at the right interval. TSH and Free T4 typically stabilize about six to eight weeks after a change. Checking too early can mislead decisions.
-
Titrate to your physiology. We adjust in small steps, usually 12.5 to 25 micrograms at a time, watching both symptoms and labs.
-
Keep timing consistent. Take levothyroxine on an empty stomach with water, then wait 30 to 60 minutes before food or coffee. Keep calcium, iron, and some supplements at least four hours away to avoid absorption issues.
For hyperthyroidism, options include antithyroid medication, definitive therapy, or, in select cases, watchful waiting if a thyroiditis is likely to self-resolve. We set clear milestones, monitor liver function and blood counts when appropriate, and watch for symptom improvement while the hormone levels normalize.
Energy, bowels, weight, skin, and heart, how thyroid shifts feel
-
Energy: If you wake unrefreshed and slow to start, think low thyroid. If you feel “amped” with poor sleep and easy fatigue after small tasks, think high thyroid.
-
Bowels: Constipation is common with low thyroid. Loose stools without infection lean high.
-
Weight: Modest weight changes are common. Large, sudden shifts point us to look for additional causes such as fluid changes or other hormones.
-
Skin and hair: Dry, rough skin or shedding with coarse hair suggests low. Smooth, warm skin with shedding and fragile hair suggests high.
-
Heart rate: A resting rate in the 50s to 60s is often normal for athletes. New bradycardia with symptoms, or resting tachycardia, merits labs and review.
These patterns help us guide next steps, but labs confirm the diagnosis.
Travel and holiday medication tips
-
Pack a “meds first” kit in your carry-on. Include at least one extra week of thyroid medication, a small pill organizer, and a copy or photo of your prescription label.
-
Time zones, keep the interval, not the clock. Aim for roughly the same 24-hour spacing between doses. If you land late, take your dose the next morning as usual.
-
Food and coffee, protect absorption. If breakfast plans are unpredictable, take levothyroxine before bed, at least three to four hours after your last meal. Consistency is key.
-
Supplements, separate by four hours. Many holiday multivitamins contain iron or calcium.
-
Missed dose? If you remember within a few hours, take it. If it is close to your next dose, skip and resume your normal schedule. Do not double up without guidance.
-
Keep numbers handy. Save your pharmacy’s phone number and our office number so we can help with refills if your travel extends.
When imaging or procedures help
If your exam reveals a nodular thyroid, a visible goiter, or if your labs and symptoms do not match, ultrasound clarifies structure in minutes. Nodules are common. Most are benign. If a nodule meets size or appearance criteria, a quick, ultrasound-guided fine needle aspiration can provide answers without hospital scheduling or stitches. At our clinic, results are reviewed with you, and next steps are set clearly.
