FROM nausea to constipation and life-threatening pancreatitis, fat jabs come with a long list of possible side effects.
But, as we revealed in Sun Health last month, there is a new complication that's come to light - putting people at risk of 'old lady's bones' and losing inches of their height.

More than 1.5million Brits are thought to be on weight loss jabs like Ozempic, including
Originally designed to treat type 2 diabetes, the jabs work by mimicking GLP-1, a hormone that's released in the body when you are full.
Known as GLP-1 RAs (receptor agonists), they work to reduce appetite and curb cravings, while also boosting insulin to help regulate

Ruth states that the safest way to lose weight is gradually, aiming for around one to two pounds (0.45 to 0.9 kg) per week.

CALCIUM is an essential mineral for strong bones.
'Adults generally need 1,000mg per day, rising to 1,200mg per day for women over 50 and men over 70,' says
But, with calorie restriction, a woman's intake of calcium usually drops, which may worsen bone loss.
According to other research in the

per day of calcium in supplement form during weight loss can help mitigate potential bone issues.

Make sure your diet contains plenty of calcium-rich foods too.
'The best sources include dairy (milk, yoghurt and cheese), canned sardines or salmon with bones, leafy greens like spinach, kale and broccoli, calcium-fortified plant milks, tofu, beans, and nuts,' says Hamza.

SUPPLEMENT SAVVY
MOST people can get the majority of their essential nutrients through a healthy diet but supplements can help in certain cases, for example, during rapid weight loss.
'People living with obesity may already have lower levels of key vitamins and minerals, which can worsen during weight loss,' explains Ruth.
'In those cases, a multivitamin and mineral supplement may be useful.
'Women going through menopause are also at higher risk of bone loss due to falling oestrogen levels, so making sure they get enough calcium and vitamin D is especially important.'

Our bodies create vitamin D in response to sufficient sunlight.
So the Government advises everyone to take a vitamin D supplement between October and April.

Vitamin D3 is best because it is more easily absorbed by the body.
CUT BACK ON UPFs

Stock up on grains, fruits and vegetables, protein and healthy fats such as avocado and nuts and seeds
LOSING weight but still eating processed foods? Your bones won't be happy.
Hazma says: 'Diets high in processed foods, sugar, salt, saturated fat and phosphate additives (these are added to processed foods to improve texture, flavour shelf life or colour) are linked to poorer bone density and higher osteoporosis risk.
'High sugar and salt intake increase urinary calcium loss, phosphate additives disrupt calcium metabolism, and processed foods often lack essential bone-building nutrients.

'Over time, these factors combine to weaken bones and elevate fracture risk.'
Instead of processed foods such as cakes, sweets, processed meats and ready meals, enjoy a predominantly whole food diet.
Stock up on grains such as brown rice, oats and brown pasta, fruits and vegetables, protein and healthy fats such as avocado and nuts and seeds.
Everything you need to know about fat jabs
Weight loss jabs are all the rage as studies and patient stories reveal they help people shed flab at almost unbelievable rates, as well as appearing to reduce the risk of serious diseases.
Wegovy – a modified version of type 2 diabetes drug Ozempic – and Mounjaro are the leading weight loss injections used in the UK.
Wegovy, real name semaglutide, has been used on the NHS for years while Mounjaro (tirzepatide) is a newer and more powerful addition to the market.
Mounjaro accounts for most private prescriptions for weight loss and is set to join Wegovy as an NHS staple this year.
How do they work?
The jabs work by suppressing your appetite, making you eat less so your body burns fat for energy instead and you lose weight.
They do this my mimicking a hormone called GLP-1, which signals to the brain when the stomach is full, so the drugs are officially called GLP-1 receptor agonists.
They slow down digestion and increase insulin production, lowering blood sugar, which is why they were first developed to treat type 2 diabetes in which patients' sugar levels are too high.
Can I get them?
NHS prescriptions of weight loss drugs, mainly Wegovy and an older version called Saxenda (chemical name liraglutide), are controlled through specialist weight loss clinics.
Typically a patient will have to have a body mass index (BMI) of 30 or higher, classifying them as medically obese, and also have a weight-related health condition such as high blood pressure.
GPs generally do not prescribe the drugs for weight loss.
Private prescribers offer the jabs, most commonly Mounjaro, to anyone who is obese (BMI of 30+) or overweight (BMI 25-30) with a weight-related health risk.
Private pharmacies have been rapped for handing them out too easily and video calls or face-to-face appointments are now mandatory to check a patient is being truthful about their size and health.
Are there any risks?
Yes – side effects are common but most are relatively mild.
Around half of people taking the drug experience gut issues, including sickness, bloating, acid reflux, constipation and diarrhoea.
Dr Sarah Jarvis, GP and clinical consultant at patient.info, said: 'One of the more uncommon side effects is severe acute pancreatitis, which is extremely painful and happens to one in 500 people.'
Other uncommon side effects include altered taste, kidney problems, allergic reactions, gallbladder problems and hypoglycemia.
Evidence has so far been inconclusive about whether the injections are damaging to patients' mental health.
Figures obtained by The Sun show that, up to January 2025, 85 patient deaths in the UK were suspected to be linked to the medicines.
LIFT WEIGHTS

Resistance exercise is one of the best things you can do to support your bones

RESISTANCE exercise is one of the best things you can do to support your bones while on GLP-1, according to the study in the journal

In the study, participants attended two group exercise sessions a week, as well as exercising on their own.
In the group sessions, participants did 30 minutes of interval-based cycling, and 15 minute circuits with both strength training and aerobic exercise.
Individual exercise was moderate-to-vigorous, such as
cycling
, running, brisk walking or circuit training.
Hamza explains: 'When muscles contract during resistance or weight-bearing exercise, they pull on tendons attached to bones, creating mechanical strain and stress on the bone tissue.
'This mechanical force is sensed by bone cells, especially osteocytes, which then signal osteoblasts (bone-forming cells) to increase bone formation and remodelling to strengthen the bone.

'Aim to do resistance or weight-bearing exercise two to three times per week, using progressive resistance (lifting heavier or more reps over time).
'Bodyweight exercises help, but adding external load - like bands, free weight or machines - creates greater mechanical stress, which is what prompts bones to adapt and densify.'
For Sophie, lifting weights twice a week is non-negotiable, with exercises including leg press, dumbbell-weighted lunges and squats.
She says: 'I do a lot of moves on a wobble board (a flat, hard top attached to a round bottom which creates instability) too.
'I also do three Pilates reformer classes a week on the heavier springs, and I walk 12 to 15 thousand
steps
each day.'

PACK IN PROTEIN
IT'S not just muscles that need protein, bones need it too.
In fact, protein actually makes up around 50 per cent of bone volume according to research in the
'Protein also helps us absorb calcium,' adds Dominika Blonska, PT and founder of
'Aim for around 1-1.5g of protein per 1lb of body weight.'
For example, a 100lb person can aim for 100-150 g of protein per day.

Meat, fish, eggs, dairy and legumes (beans, lentils, peas) are great options.
For vegans, Ruth suggests tofu, tempeh, edamame and fortified plant-based milks.
CUT BACK ON BOOZE
ALCOHOL and sugary drinks such as Coke won't do your waistline any favours.
But they could also damage your bones.
'Alcohol slows down calcium absorption and increases the risk of fractures,' says Dom.

'The phosphoric acid in sugary, fizzy drinks is linked to lower bone density.'

Dom adds: 'Caffeine (in fizzy drinks and coffee) also affects calcium absorption - therefore, try to limit to one to two cups of caffeine per day.'
MAGNESIUM MATTERS

Foods rich in magnesium include nuts, seeds, whole grains, bananas, dried apricots and soy products such as milk and tofu.

The top foods for healthy bones
EATING a balanced diet will help to keep your bones healthy.
This means plenty of fruit, vegetables, protein, healthy fats and sufficient calcium and vitamin D.
Not getting enough of these things can cause conditions like rickets and osteoporosis, and increase your risk of breaking bones later in life.
Adults need 700mg of calcium a day. It can be found in foods and drinks like:
Milk, cheese and other dairy
Green leafy vegetables (e.g. as broccoli, cabbage and okra, but not spinach)
Soya beans
Tofu
Fortified plant-based drinks (e.g. soya drink)
Nuts
Bread and anything made with fortified flour
Fish where you eat the bones (e.g. sardines and pilchards)
The recommended daily intake for vitamin D for adults in the UK is 10 micrograms (or 400 International Units, or IU).
As it's difficult to get all the vitamin D we need from our diet, and we get most of it from the sun, we should all take daily supplements from October to March.
Vitamin D can also be found in:
Oily fish (e.g. salmon, sardines and mackerel)
Egg yolks
Fortified foods (e.g. some fat spreads and breakfast cereals)
