Erectile dysfunction (ED) affects millions of men and becomes more common with age. However, ED isn’t simply an unavoidable part of getting older. In many cases, it’s one of the first signs that something else in your body deserves attention.
The good news? Most men respond well to treatment.
At Flow Wellness, we don’t just write a prescription and send you on your way. Instead, we look for why ED is happening and create a personalized treatment plan that improves both sexual health and overall wellness.
More importantly, you don’t have to wait for weight loss, hormone optimization, or lifestyle changes before seeing results. We treat the symptoms right away with proven medications while working to correct the underlying causes for lasting improvement.
What Doctor Should You See for Erectile Dysfunction?
Several healthcare providers diagnose and treat erectile dysfunction, including:
- Primary care providers
- Urologists
- Men’s health providers
- Obesity medicine specialists
- Hormone specialists
The right provider depends on the cause of your symptoms.
For example, if ED is related to obesity, diabetes, low testosterone, high blood pressure, or cardiovascular disease, treating those conditions often improves erections as well. That’s why a comprehensive evaluation is just as important as prescribing medication.
What Causes Erectile Dysfunction?
An erection requires healthy blood vessels, balanced hormones, functioning nerves, and proper communication between the brain and the penis. When any part of that system is affected, erectile dysfunction can develop.
Common causes include:
- Obesity
- Diabetes
- High blood pressure
- High cholesterol
- Low testosterone
- Smoking
- Sleep apnea
- Anxiety or depression
- Certain medications
- Cardiovascular disease
- Aging
Many men have more than one contributing factor, which is why ED often requires more than a one-size-fits-all solution.
Obesity Is One of the Biggest Risk Factors
Although age increases the risk of ED, obesity plays an equally important role.
Research shows that obesity and aging are independent, additive risk factors for erectile dysfunction.
Overweight men have approximately 1.5 to 2.5 times the risk of developing ED compared with men at a healthy weight, and symptoms often become more severe as body fat increases.

That’s because excess body fat contributes to:
- Poor blood vessel function
- Chronic inflammation
- Insulin resistance
- Lower testosterone levels
- Increased cardiovascular disease risk
Together, these changes reduce blood flow and make it more difficult to achieve or maintain an erection.
Can Losing Weight Improve Erectile Dysfunction?
Absolutely.
Weight loss improves far more than the number on the scale. Studies show it can significantly improve erectile function by improving circulation, reducing inflammation, increasing insulin sensitivity, and supporting healthier testosterone levels.
As a result, many men notice improvements in both their overall health and sexual performance.
This is one reason GLP-1 medications like tirzepatide and semaglutide have become such valuable tools. By improving metabolic health and reducing excess body fat, they often address several of the root causes of erectile dysfunction at the same time.
How Do Doctors Diagnose ED?
Most evaluations begin with a conversation. But, don’t worry—this isn’t a long or awkward conversation.
Your provider will ask a few simple questions, many of which you can answer with just a few words. We may ask about when your symptoms started, your sex drive, morning erections, medications, medical history, and lifestyle habits.
Depending on your history, we may also order labs such as testosterone, A1C, cholesterol, and thyroid levels.
Because ED can be an early sign of heart disease, we’ll also evaluate your overall cardiovascular health.
First-Line Treatment: Sildenafil and Tadalafil
For most men, treatment starts with a PDE5 inhibitor.
These popular medications increase blood flow to the penis, making it easier to achieve and maintain an erection during sexual stimulation.
The two most common options are:
- Sildenafil (Viagra®)
- Tadalafil (Cialis®)
Overall, studies show that 60–80% of men experience improved erections with these medications.
However, success depends on the underlying cause of ED. Men with severe vascular disease, advanced diabetes, nerve injury, or significant hormone deficiencies may also need additional treatment.
Sildenafil (Viagra)
Sildenafil is an excellent option for planned sexual activity. It usually starts working within 30 to 60 minutes and lasts about 4 to 5 hours.
Many patients choose sildenafil because it’s affordable, effective, and only needs to be taken when needed. However, high-fat meals may delay its absorption, and its shorter duration requires more planning.
Tadalafil (Cialis)
Tadalafil offers greater flexibility.
Although it takes a similar amount of time to start working, its effects can last up to 36 hours, allowing for greater spontaneity. Additionally, low-dose daily tadalafil provides continuous support and may improve urinary symptoms caused by an enlarged prostate.
Many patients prefer tadalafil because food has little effect on absorption, and daily dosing eliminates the need to plan ahead.
Is Low Testosterone Causing Your ED?
Sometimes—but not always.
Low testosterone may contribute to reduced libido, fatigue, lower energy, and difficulty maintaining erections. However, testosterone isn’t the most common cause of ED.
In fact, many men with normal testosterone levels develop erectile dysfunction because of obesity, diabetes, vascular disease, or medication side effects. Therefore, testosterone testing should be part of a comprehensive evaluation rather than the only test performed.
Lifestyle Still Matters
Although medication can work quickly, long-term results depend on improving your overall health.
We encourage patients to:
- Lose excess body fat
- Build muscle with resistance training
- Eat adequate protein
- Sleep 7–9 hours each night
- Limit alcohol
- Quit nicotine
- Control blood pressure and blood sugar
Together, these changes improve circulation, support hormone health, and often enhance sexual performance.
Flexible and Private Treatment Options
At Flow Wellness, you have options.
We can send your sildenafil or tadalafil prescription to your local pharmacy for affordable and fast prescription pick up that can be run through your insurance. Or, if you’d prefer greater privacy, we can have it filled through a trusted compounding pharmacy and shipped directly to your home.
Additionally, many patients combine tadalafil with treatments such as testosterone replacement therapy or growth hormone peptides, like sermorelin, making their treatment plan even more convenient. Many patients also appreciate the added privacy that comes with using a compounding pharmacy rather than a traditional retail pharmacy.

Frequently Asked Questions
Is erectile dysfunction a normal part of aging?
No. While ED becomes more common with age, it’s often caused by treatable medical conditions such as obesity, diabetes, high blood pressure, or low testosterone.
Does Viagra or Cialis cure ED?
No. These medications improve blood flow and help you achieve an erection, but they don’t treat the underlying cause. That’s why addressing your overall health is so important.
Can losing weight improve erectile dysfunction?
Yes. Weight loss can improve blood flow, hormone balance, and cardiovascular health, all of which may improve erectile function.
Which works better: Viagra or Cialis?
It depends. Viagra works well for planned intimacy, while Cialis lasts up to 36 hours and offers greater spontaneity. Your provider can help you decide which is the best fit.
Do I need lab work?
Sometimes. Depending on your symptoms and medical history, your provider may recommend labs to check for low testosterone, diabetes, cholesterol problems, or other underlying conditions.
