Genes and Your Family Story

Your genes don’t determine your fate, but they do shape your starting point. A strong family history of certain conditions can increase your risk — but knowing about this early helps you take action through screening and/or lifestyle change to protect your future health.

We assess family history risk in Thrive and include relevant risk scores and recommendations in your personalised plan.

Heart Disease (including Heart Attack, Stroke, High Blood Pressure)

Genetic Links:

A strong family history includes heart attacks or strokes in men under 55 or women under 65.

What to look for:

Parents, siblings, or close relatives with early cardiovascular events or diagnoses (e.g. stents, bypass surgery, stroke).

Tip:
If you have a family history, it’s especially important to monitor blood pressure, cholesterol, and metabolic markers regularly — and to start prevention early.

Alzheimer's and Other Dementias

Genetic Links:

Family history increases your risk, particularly if a parent or sibling was diagnosed before age 80.

What to look for:

Memory loss or dementia in a first-degree relative.

Tip:
Lifestyle matters! Staying mentally and physically active, keeping blood pressure in check, and eating a Mediterranean-style diet can delay or reduce risk substantially.

Type 2 Diabetes

Genetic Links:

Strong family history if one or more first-degree relatives have diabetes.

What to look for:

Parents, siblings, or grandparents diagnosed with type 2 diabetes.

Tip:
Even with a strong genetic predisposition, weight management, physical activity, and healthy eating can significantly reduce your risk.

Fatty Liver Disease (MAFLD)

Genetic Links:

Emerging evidence suggests genetic variants may make some people more susceptible.

What to look for:

Family members with fatty liver, liver inflammation, or unexplained abnormal liver tests.

Tip:
Keep alcohol intake, visceral fat (this is the hidden fat stored deep inside your abdomen that releases chemicals that disrupt your hormones and increase inflammation) and triglycerides in check with regular physical activity and a diet low in refined carbs and added sugars.

Obstructive Sleep Apnoea

Genetic Links:

Strongly influenced by anatomical and hereditary traits (e.g. neck shape, upper airway anatomy).

What to look for:

Close relatives with sleep apnoea, loud snoring, or CPAP use.

Tip:
If you have risk factors or daytime fatigue, ask for a sleep assessment. Focusing on healthy lifestyle can reduce your risk dramatically.

Osteoporosis & Osteoarthritis

Genetic Links:

Family history is a major contributor, especially for postmenopausal women.

What to look for:

Hip fractures in relative younger than 80 or hip or knee replacements in relatives younger than 65, spinal curvature, or osteoporosis in parents/siblings.

Tip:
Strength training, regular exercise, adequate calcium and vitamin D, and regular bone density scans (DXA) to monitor bone strength for those at risk.

Breast & Ovarian Cancer

Genetic Links:

BRCA1/2 mutations increase risk substantially, especially with early onset or multiple cases in the family.

What to look for:

Breast or ovarian cancer in multiple family members, especially under age 50.

Tip:
If concerned, genetic counselling or screening can help determine risk and screening plans.

Prostate Cancer

Genetic Links:

Risk doubles with a first-degree relative affected, especially if diagnosed young.

What to look for:

Prostate cancer in father, brother, or uncle before age 50.

Tip:
Discuss screening options early with your GP, especially if you’re over 45.

Glaucoma & Macular Degeneration

Genetic Links:

Both conditions run in families.

What to look for:

Vision loss, glaucoma, or macular degeneration in parents or siblings.

Tip:
Regular eye checks are critical — early detection can preserve vision.

Bowel Cancer

Genetic Links:

Especially important if diagnosed in family before age 50 or multiple people diagnosed.

What to look for:

Bowel cancer or large polyps in close relatives.

Tip:
You may need to start screening earlier than the general population. We’ll provide recommendations specific to your situation and talk to your GP.

Thrive Tips:

Many cancers share modifiable risk factors — especially poor diet, smoking, inactivity, alcohol, and inflammation. Thrive’s screening and goal-setting tools help you act before symptoms arise.
