Many Africans abroad work long hours, sleep too little, eat on the go and carry the stress of supporting families in two countries. Combined with genetic and lifestyle factors, this can increase the risk of high blood pressure and type 2 diabetes. These conditions often have no symptoms at first, which is why they’re sometimes called silent killers.
This guide provides general information. Speak to your doctor about your personal risk and any symptoms.
Why This Matters for Africans Abroad
Health research in several countries shows that people of Black African and Caribbean heritage tend to have higher rates of high blood pressure and may develop type 2 diabetes at younger ages than some other groups. Changes in diet, activity and stress after migration can add to these risks.
High Blood Pressure
High blood pressure (hypertension) increases the risk of stroke, heart disease and kidney problems. Most people feel fine until complications develop. The only way to know is to get checked.
The British Heart Foundation provides information on blood pressure, heart health and reducing risks.
Type 2 Diabetes
Type 2 diabetes affects how your body uses sugar. Possible symptoms include increased thirst, frequent urination, tiredness and slow-healing wounds, but many people have no obvious symptoms. Untreated diabetes can damage the eyes, kidneys, nerves and heart.
Get Screened
- Check your blood pressure regularly at your doctor’s surgery, pharmacy or with a home monitor
- Ask about diabetes screening, especially if you have a family history or are overweight
- Attend health checks when invited
- Know your numbers and track them over time
Food: Keep the Culture, Adjust the Portions
You don’t have to abandon Nigerian or African food to eat healthily. Practical adjustments include:
- Reduce salt and stock cubes in soups and stews
- Use less palm oil and vegetable oil
- Eat smaller portions of swallows like eba, pounded yam and fufu
- Add more vegetables and leafy greens
- Choose grilled fish or lean meat over fried options
- Limit sugary drinks, including soft drinks and malt
- Watch party food and small chops
Move More
Regular physical activity helps control blood pressure, blood sugar and weight. Walking, cycling, dancing, swimming and gym classes all count. Build movement into daily life, such as walking part of your commute.
Manage Stress and Sleep
Stress and poor sleep can affect blood pressure and blood sugar. Protect your rest, set boundaries on work and family demands, and talk to someone when pressure builds.
Take Medication as Prescribed
If your doctor prescribes medication, take it consistently. Some people stop when they feel better or rely only on herbal remedies. Never stop prescribed medication without speaking to your doctor.
Watch Out During Trips Home
Trips home can involve rich food, heat and disrupted routines. Take enough medication, keep checking your readings where possible and continue healthy habits.
Talk About It in Your Community
Churches, mosques and community groups can host health checks and talks. Encourage family members, including parents back home, to get screened.
Know When to Seek Urgent Help
Seek emergency care for chest pain, sudden weakness, facial drooping, slurred speech, severe headaches or confusion. Quick action can save lives.
Encourage Parents Back Home
Many Nigerian parents don’t check their blood pressure or blood sugar regularly. Consider buying them a home blood pressure monitor, encouraging regular clinic visits and discussing results with them. Support from abroad can help prevent strokes and other serious complications.
Final Thoughts
High blood pressure and diabetes are common but often preventable and manageable. Get screened, know your numbers, adjust your diet without losing your culture, move more and take prescribed medication. Your health is your most valuable asset abroad.
