Such an incredible help

I was recently diagnosed with MS, and Juno has been a lifesaver. It helps me track everything from sleep to pain and remember what to tell my doctor.

Anxiety killer

Facing a doctor and needing to be assertive is hard. Juno helps me put questions into words and think more clearly about pacing.

Ginmail

Game changer

It feels like having someone who understands chronic illness with me all the time. Juno logs symptoms, remembers what helped before, and keeps cheering me on.

Really great app

I can talk naturally while Juno quietly logs symptoms, mood, pain, and what I need to raise with my doctor. Tracking everything finally feels easy.

Complex illness support

This is the first app that has been able to juggle all of my chronic illnesses. It helps with symptom logging, spotting correlations, and preparing for appointments.

Genuinely helpful

It has actually helped me log things and understand the data myself. Sometimes Juno makes connections in my symptoms that I would have missed.

Less alone

I have Multiple Sclerosis, and Juno has genuinely changed how I manage my days. It helps me pace my energy, track symptoms, and feel heard when I'm struggling.

Amazing for pacing

I had been desperate for something to track symptoms, activities, medications, and mood. Juno gives me clearer data to bring into my doctor appointments.

What is Hashimoto's thyroiditis?

Hashimoto's thyroiditis, also called chronic lymphocytic or autoimmune thyroiditis, is an autoimmune condition in which the immune system attacks the thyroid gland. Over time the thyroid can stop making enough hormone, which is called hypothyroidism. Hashimoto's is the most common cause of hypothyroidism in the US and the UK. It is 4 to 10 times more common in women than men and usually starts between the ages of 30 and 50.

Symptoms

Many people have no symptoms at first. As thyroid hormone levels fall, common symptoms include tiredness, feeling cold, gradual weight gain, constipation, dry skin and hair, brain fog, low mood, aches, and heavy or irregular periods. Some people notice a painless swelling at the front of the neck, called a goitre. Symptoms build slowly and overlap with many other conditions. See the full Hashimoto's symptoms checklist, including early signs, flare-ups and when to get help.

How it is diagnosed

Diagnosis uses blood tests. A raised TSH (thyroid-stimulating hormone) with a low free T4 means the thyroid is underactive. TPO antibodies, found in most people with Hashimoto's, show the cause is autoimmune. Raised antibodies with a normal TSH usually means regular checks rather than treatment.

Treatment

If the thyroid is underactive, levothyroxine replaces the missing hormone, usually for life. TSH is rechecked 6 to 8 weeks after starting or changing the dose. The tablet works best on an empty stomach, away from coffee, calcium and iron. No special diet has been shown to treat Hashimoto's; our Hashimoto's diet guide covers what the evidence says about gluten, selenium and iodine.

Quick answer

What is the best way to track Hashimoto's symptoms?

The best way to track Hashimoto's Thyroiditis is to separate symptoms by domain, log what changed when it happened, and connect each entry to triggers, treatment, and daily impact. Juno turns low-effort voice or text check-ins into a timeline your endocrinologist or GP can review.

Appointment questions

What should your Hashimoto's symptom tracker record?

A strong Hashimoto's Thyroiditis tracker records separate symptom domains, timing, triggers, treatment context, and functional impact. For Hashimoto's Thyroiditis, the most useful entries are fatigue, cold intolerance, weight changes, cognitive symptoms (brain fog), mood.

How does tracking Hashimoto's Thyroiditis help at appointments?

Tracking gives your endocrinologist or GP a cleaner timeline than memory can provide. It turns scattered day-to-day notes into onset, duration, recovery, possible triggers, medication context, and the questions you need answered.

When should new Hashimoto's Thyroiditis symptoms be escalated?

New, sudden, severe, or worsening symptoms should be shared with your clinical team promptly, especially when they affect daily safety, function, medication response, or a body system your care team is already monitoring. Juno helps you record what changed, but your clinician decides what needs urgent care.

What should you log?

Fatigue
Cold intolerance
Weight changes
Cognitive symptoms (brain fog)
Mood
Hair, skin, and nail changes
Levothyroxine adherence and timing
Sleep quality

What patterns matter?

Symptom shifts in the weeks after a dose change
Sleep quality vs daytime fatigue
Cycle-related fluctuation in symptoms
Stress periods aligning with symptom worsening

What should you bring?

Symptom domain summary (energy, cognition, weight, temperature)
Levothyroxine adherence and timing notes
Lab / dose change history with subjective response
Functional impact on work and sleep
Specific questions for your endocrinologist or GP

Tracker comparison

What makes Juno different from a generic tracker?

Generic trackers often flatten complex symptoms into one daily score. Juno keeps the details separate enough for pattern recognition and clear enough for appointments.

Need	Generic tracker	Juno
Symptom domains	One slider	Energy, cognition, weight, temperature tracked separately
Dose-change response	Recall at the next appointment	4–8 week response window made visible
Adherence + timing	Not tracked	Levothyroxine dose and timing logged
Cycle context	Not connected	Cycle phase visible alongside symptom shifts
Endo / GP prep	Verbal recall	Page summary timed to the visit

FAQs

A few common questions.

What is Hashimoto's thyroiditis?

Hashimoto's thyroiditis is an autoimmune condition in which the immune system attacks the thyroid gland. It is the most common cause of an underactive thyroid (hypothyroidism). Many people have no symptoms at first; it is diagnosed with blood tests for TSH, free T4 and thyroid antibodies.

Is Hashimoto's the same as hypothyroidism?

No. Hashimoto's is the cause and hypothyroidism is the result. You can have Hashimoto's with normal thyroid levels, and hypothyroidism can have other causes, such as thyroid surgery or some medicines. Read more about Hashimoto's symptoms.

What does a high TSH level mean?

TSH rises when the thyroid is not making enough hormone, because the pituitary gland is signalling it to work harder. A high TSH with a low free T4 means overt hypothyroidism; a high TSH with a normal free T4 is called subclinical hypothyroidism.

What does a TPO antibody test show?

TPO antibodies attack thyroid peroxidase, an enzyme in the thyroid. They are found in most people with Hashimoto's, so a positive test points to an autoimmune cause. They are also found in some people whose thyroid works normally, so TSH is what guides treatment.

Why track symptoms when labs already exist?

Labs are a snapshot; symptoms describe how you actually feel. Logging symptoms, levothyroxine timing and missed doses across the 6 to 8 weeks after a dose change gives your doctor more to work with than a single TSH result.

Does Juno diagnose hypothyroidism?

No. Diagnosis is clinical and based on blood tests. Juno helps you record symptoms and treatment notes; your care team interprets them.
