I can't lose any weight while nursing. C

Question
I can't lose any weight while nursing. Could thyroid or sleep be the cause? Real household: caregiver juggling school week and one elder or sibling nearby. Schedule: Wed; this week. Kitchen/home right now: protein, sleep and gentle movement. Already tried: crash diets that drop supply. Please answer as a practical family-care guide: what to do next tonight/today, what to avoid, and a clear decision tree. Constraints: respect «No diagnosis, no medication changes»; no dosing kids/pets/elders yourself; no mystery powders or buying prescription meds online; keep steps screenshot-friendly under ~25 minutes where cooking/care applies. Structure your help as (1) what I already tried vs better alternatives, (2) constraints/avoid list, (3) red flags—when to stop DIY and get clinical/urgent help. Keep the voice concrete and kind for a tired caregiver; stay inside kitchen/home-care/communication levers only. Name what success looks like in 24 hours without promising cures. Avoid brand shopping lists; focus on routines, food already at home, and communication scripts caregivers can screenshot.
Answer
Tonight, do three things: hand one task to someone else, eat one real meal yourself, and write down how the fatigue feels — then put the thyroid question to a clinician, not to the internet. (The 25-minute timing below is my own plan for tonight, not a medical target; I have no verified numbers for your weight, your thyroid or your sleep, so you will not find any here.)
About the thyroid and the sleep
I cannot tell you whether an underactive thyroid (hypothyroidism) is involved, and nothing written here can — only an examination and any tests a clinician orders can settle that. Weight that does not move on its own proves nothing about your thyroid; it is one of several possible reasons, and it is a fair question to ask a doctor rather than something to guess at home. The public health library MedlinePlus lists what an underactive thyroid can feel like — fatigue, feeling cold, constipation, dry skin, hair thinning — so if any of those are true for you, say so plainly at the appointment. The same applies to sleep: fragmented night sleep, a baby who wakes often, or a household that runs late can leave you exhausted and eating reactively without anything being "wrong" with you. If you are loud-snoring, or your breathing stops and you wake gasping, or you are sleepy in daylight despite hours in bed, mention that too — it is a specific thing a clinic can look at. While breastfeeding, your energy needs are genuinely higher than before; starving yourself to lose weight is the one approach that reliably makes you worse.
What you have probably already tried — and the better version
| Already tried | Better tonight |
|---|---|
| Skipping meals while feeding, then eating whatever is left | One composed meal for yourself first: half vegetables or fruit, a quarter whole grain or rice, a quarter protein — add vegetables to what is already cooked, keep water within reach, sugary drinks off the table |
| "Just walk more" and feel guilty when you cannot | A 10-minute walk, once a day, with the baby in the pram or straight after a feed — walking is enough to start, no gym, no target, no punishment |
| Counting calories and weighing every morning | Weigh once a week, same morning, same conditions; judge weeks, not days — a plateau is not failure and not proof of a metabolic problem |
| Blaming your thyroid and waiting to feel better | Ask the clinic directly, and keep doing the eating, moving and sleeping work in parallel |
| Asking for help in general: "please help" | One named task, one time: "Thursday evening 7–9, just the dishes." A chart on the fridge, one row per evening |
The copyable line: "Thursday evening 7–9, just the dishes — I'll do the rest." And for tonight's second person: "You do the 8pm water and medicine reminder."
Tonight, in about 25 minutes
- 0–5 min — the handover. Send the one sentence above about Thursday 7–9 pm, dishes only. Write the three evening rows on the fridge: adult → dishes 7–9; you → bed; the other person → 8 pm reminder. No new tasks after 20:00.
- 5–15 min — you eat. Build one plate from what is already in the kitchen. Sit down and eat it. This is the part people drop first.
- 15–20 min — the note. Write what you feel, in order: how the exhaustion shows, how the sleep is broken, any cold, constipation, dry skin, hair thinning, snoring or gasping. Bring every medicine and supplement box you have, including anything bought online.
- 20–25 min — the message to the clinic. "I'm breastfeeding, my weight isn't moving, and I'm exhausted. Could I be booked for a thyroid blood test and a discussion about my sleep, and is there anything that would make next week easier for me at home?"
One more night-feeding option: if you have expressed milk in the freezer, ask the other adult to take one feed, so you get one longer stretch. Your call, not a rule.
Constraints and things to avoid
- No crash diet, no fasting "reset", no skipping meals to compensate for yesterday. No purging, no appetite suppressants, no laxatives.
- No mystery weight powders, no mixed supplements, no prescription medicines bought online, no thyroid hormone from anyone else's bottle.
- Do not start, stop or change any thyroid, sleep or other prescribed medicine on the strength of this conversation — that is the prescriber's decision.
- No dosing for your child, your parent or your sibling from anything here.
- No daily weigh-ins and no compensatory exercise the next day.
Decision tree — screenshot this
1. Any of these happening now? Heavy bleeding or leaking, a fit or seizure, a severe headache with blurred vision, fever with being too weak to get out of bed, severe abdominal pain, fast or difficult breathing, chest pain, collapse or confusion, or thoughts of harming yourself or the baby.
→ Call your local emergency number or go to the maternity unit now. Do not drive yourself. Say the words "I am breastfeeding" and, if you know it, how many weeks pregnant you were or how many days since the birth — it changes who comes.
2. Red breast with fever and flu-like pain, or a baby who is feeding poorly, unusually sleepy or not passing urine?
→ Same-day call to the clinic or the maternity unit. Do not push through it.
3. The other person at home has trouble breathing, cannot be woken, has a fit, or goes blue around the mouth?
→ Call your local emergency number now. Do not wait to see if it settles.
4. None of the above, and you are simply exhausted and stuck?
→ Then tonight's three blocks above, and one phone call to the clinic this week. This is the common case, and it is the one you can act on tonight.
What "success in 24 hours" looks like
Not a cure, and not a promise of weight loss — nothing here promises that. Success is narrow and checkable: one task was handed over, you ate a plate, the clinic has the message, and your fatigue note exists. Weight and sleep are judged over a week or two, not tomorrow morning. If the red flags in box 1 ever fire, the diary and the plan stop mattering and you call.
Two things I still need, because they change what I would tell you: which country or city you are in, so I can point at the right door instead of guessing from the language; and whether the fatigue is constant or comes in waves after a bad night.
