Managing Your Calcium Levels: A Simple Guide
1. Keep your calcium “topped up”
Think of your body like a toy that needs the right amount of winding—not too little and not too much.
You need enough calcium each day to feel well. You can keep your levels steady by:
Taking your medication exactly as prescribed
Eating calcium-rich foods
Having small calcium snacks between meals if you’re prone to dips
Taking a little extra calcium before exercise if you usually drop afterwards
Don’t take more than you need—it’s easy to add a little later, but hard to fix an overdose.
2. Listen to your body
You know your body best. Don’t ignore symptoms that feel unusual.
If you feel your calcium is changing, take action early.
3. Learn your symptoms
Hypopara affects everyone differently. Early signs of low calcium can include:
Feeling unusually irritable
Getting cold suddenly
Feeling twitchy or restless
Needing to use the loo urgently
Becoming sensitive to noise
As levels drop further, you may feel:
Tingling or numbness in your hands, feet, or face
Twitching
A “vibrating” feeling inside
Cramps (for some, this is the first sign)
Whatever your symptoms are, learn them—they are signals that you need to act.
4. Stop the drop early
Early symptoms mean your calcium is starting to go too low (or sometimes too high).
Act quickly:
Try a small top-up, like milk or a small part of your calcium tablet
Many people do better when their calcium dose is split across the day
Sometimes you only need to take your usual dose earlier than planned
If symptoms keep coming back for several days, your medication may need adjusting. Contact your endocrinologist.
Ignoring symptoms can let levels slowly drift too low or too high, leading to a sudden “hypo”—a drop that’s harder to control on your own.
5. What is a “hypo”?
A hypo (hypocalcaemic crash) is when your calcium drops quickly and your symptoms get severe.
Sometimes this happens even when you’ve done everything right—it’s not your fault.
If you feel a bad hypo coming and can’t control it, get a blood test urgently. If that’s not possible, go to A&E with your emergency card.
You may need intravenous calcium (a drip) to bring your levels back up.
6. What to do during a hypo
At home:
Take any calcium or medication due at that time
Consider taking an extra calcium tablet
Eat calcium-rich foods or drink milk
Keep warm
Stay calm and breathe slowly (low calcium makes you anxious, and anxiety can make calcium drop even more)
Rest and wait—calcium can take up to an hour to work
If things are not improving:
Take another calcium tablet
Call an ambulance or go to A&E for a blood test and treatment
You may need magnesium or vitamin D checked as well
7. Getting the best from your medication
Your dose of alfacalcidol or calcitriol should be high enough to let you absorb calcium from food without needing lots of supplements. This helps protect your kidneys.
You might still need calcium tablets for occasional top-ups or emergencies.
If your dose is too low or too high, you will feel unwell. Very high or very low calcium can be dangerous.
In this case, contact your GP or endocrinologist or go to A&E for blood tests and treatment.
Medication changes should be small and gradual. Sudden changes can push your levels too high or too low. Ask for regular blood tests during any adjustment.
8. What to do in an emergency
If you have a severe hypo that does not improve with extra calcium:
Call an ambulance or go to A&E
Tell staff your medical history
You will have blood tests
If calcium is very low, you will receive intravenous calcium
You may also receive magnesium
An ECG may be done to check your heart
