Understanding Cholesterol in Women Over 40
If your cholesterol levels have suddenly increased in your mid-40s, you’re not alone—and it’s not just about diet.
For many women, hormonal shifts, especially declining oestrogen during perimenopause and beyond, play a major role in cholesterol balance. In this blog, written by Lorraine English, head Clinical Nutritionist at Wellness Zone Warwick, Perth, talks about how cholesterol works, why it changes during menopause, and how nutrition, gut health, and Traditional Chinese Medicine (TCM) approaches at Wellness Zone Warwick can help you take back control.
Cholesterol is essential for your body—it supports hormone production, cell structure, and digestion. However, imbalances—especially elevated LDL cholesterol—can increase cardiovascular risk. For women over 40, these changes often accelerate due to hormonal shifts, especially a reduction in oestrogen through perimenopause and menopause.
Where Does Cholesterol Comes From?
Your body produces most of its cholesterol internally, with only a small amount coming from food.
- Your liver makes most of your body’s cholesterol each day
- A smaller portion comes from food, mainly animal-based products (meat, eggs, dairy)
- The liver also turns cholesterol into bile acids that help digest dietary fats
How Cholesterol Travels in the Body – Understanding how cholesterol moves helps explain why levels can rise:
- After eating: fats and cholesterol are packaged into chylomicrons and transported through the bloodstream
- The liver produces VLDL, which delivers triglycerides to tissues
- As VLDL loses fat, it becomes LDL (“bad” cholesterol)
- HDL (“good” cholesterol) collects excess cholesterol and returns it to the liver
- Cholesterol exits the body via bile and stool
Why Cholesterol Rises in Your Mid-40s
Many women notice a sudden spike in cholesterol during their 40s—even without changes in diet or lifestyle. This is largely due to hormonal changes. Oestrogen plays a protective role in cholesterol regulation:
- It helps maintain healthy LDL receptor activity (clearing cholesterol from the blood)
- It supports higher HDL (“good” cholesterol)
- It reduces cholesterol production in the liver
As oestrogen declines during perimenopause:
- ↑ LDL levels often increase
- ↓ HDL may decrease
- Cholesterol clearance becomes less efficient
This is why cholesterol can rise suddenly in the mid-40s—even in otherwise healthy women. During menopause, declining oestrogen shifts also alter where our fat will be stored, moving it away from the hips and thighs and promoting greater storage in the abdominal (visceral) region. This change reduces the body’s ability to efficiently clear and utilise post-meal fats, leading to higher circulating triglycerides. As a result, fat is more readily stored rather than burned, contributing to increased central weight gain and insulin resistance.
The Gut–Cholesterol Connection
Your gut microbiome plays a powerful role in cholesterol balance:
- Bile recycling: Less reabsorption means the liver uses more cholesterol → lowering LDL (1)
- Microbial enzymes (BSH): Modify bile acids and influence cholesterol metabolism (2)
- Short-chain fatty acids (SCFAs): Produced from fibre → reduce liver cholesterol production (3)
- Inflammation: Poor gut health increases cholesterol and triglycerides (4)
- TMAO production (trimethylamine N-oxide) a compound produced when gut bacteria metabolise nutrients like choline and carnitine, and higher levels are associated with increased cardiovascular risk due to effects on cholesterol metabolism and inflammation (5)
A healthy gut microbiome helps regulate cholesterol by reducing inflammation and improving bile metabolism.
Nutrition & Lifestyle Strategies to Lower Cholesterol
The good news: even with hormonal and genetic influences, cholesterol is highly responsive to diet and lifestyle.
The Power of Fibre & Diet
Soluble fibre is one of the most effective tools:
- Binds bile acids → forces the body to use cholesterol → lowers LDL
- SCFAs produced by your gut mricoebime feeding on the soluble fibre → signal the liver to reduce cholesterol production
Aim for 25–30g fibre daily (5–10g soluble fibre)
Best foods to include:
- Oats, barley, lentils, chickpeas
- Apples, citrus, berries
- Okra, eggplant, Brussels sprouts
- Ground flaxseed
- Extra virgin olive oil and oily fish
Dietary principles:
- Reduce saturated fats (butter, cream, fatty meats)
- Avoid trans fats
- Include healthy fats (olive oil, nuts, seeds, avocado)
- Limit refined sugars and processed foods
Genetics, Lifestyle & Gut Health
Genetics influence cholesterol—but they are not destiny.
- LDLR, ApoB, PCSK9, and ApoE genes affect cholesterol metabolism
- Lifestyle can significantly offset genetic risk
- Exercise improves HDL and reduces triglycerides
- Weight management improves insulin and lipid balance
Putting it all together:
- Increase soluble fibre → lowers LDL
- Improve gut health → reduces cholesterol production
- Choose healthy fats → improves lipid profile
- Stay active → supports overall cardiovascular health
Acupuncture & Chinese Herbal Medicine for Cholesterol Support
At Wellness Zone Warwick Perth, acupuncture and Chinese Herbal Medicine provide a complementary approach to cholesterol management—especially for women navigating hormonal changes.
How Acupuncture Helps Lower Cholesterol.
Acupuncture works by regulating key systems involved in cholesterol metabolism:
- Improves circulation and supports cardiovascular function (6)
- Supports healthy lipid metabolism as part of a balanced diet (7)
- Reduces inflammation linked to elevated cholesterol (8)
- Regulates blood pressure (9)
From a biomedical perspective, acupuncture may influence liver function, improve insulin sensitivity, and support nervous system regulation—all of which play a role in cholesterol balance.
Traditional Chinese Medicine
In Traditional Chinese Medicine, high cholesterol is often linked to patterns such as:
- Dampness and Phlegm accumulation (linked to poor digestion and sluggish metabolism)
- Liver Qi stagnation (stress and emotional imbalance affecting metabolism)
- Spleen deficiency (impaired digestion leading to accumulation)
TCM treatment principles focus on:
- Strengthening digestion (Spleen Qi)
- Moving Liver Qi to improve metabolic flow
- Clearing Dampness and Phlegm
- Supporting circulation and blood flow
This holistic approach works alongside nutrition and lifestyle strategies to address the root cause, not just symptoms.
Evidence-Based Supplements for Cholesterol Support
Alongside diet and lifestyle, targeted supplementation can provide additional support. Most Effective Supplements
- Plant sterols/stanols: Reduce LDL by 8–15% (10)
- Psyllium & beta-glucans: Lower LDL by 5–10% (11)
- Berberine: Improves LDL clearance and insulin sensitivity (12)
- Red yeast rice: Can reduce LDL by 15–25% (requires supervision) (13)
Additional Supportive Options
- Omega-3 fatty acids: Lower triglycerides and inflammation
- Niacin: Raises HDL and lowers LDL (clinically supervised)
- Garlic extract: Modest LDL reduction
- CoQ10: Supports heart health
- Green tea extract & curcumin: Mild lipid improvements
Conclusion
Cholesterol balance is influenced by multiple factors—your liver, gut health, genetics, lifestyle, and importantly, hormonal changes in your 40s. For women navigating perimenopause, understanding the role of oestrogen is key to making sense of rising cholesterol levels. The good news is that targeted nutrition, gut support, lifestyle changes, and integrative therapies like acupuncture and Chinese Herbal Medicine can significantly improve your cholesterol profile—naturally and effectively. At Wellness Zone Warwick Perth, we take a personalised, evidence-based approach to help women over 40 optimise their metabolic and cardiovascular health.
