Diabetics Get No Help From Testosterone Shots

Overview

Testosterone is a hormone (a chemical messenger) that men need for sex drive, strong muscles and bones, energy and mood. Low testosterone, sometimes called hypogonadism, means the body is not making enough of it. Many men with type 2 diabetes have lower testosterone than other men. Researchers have tested whether testosterone treatment helps these men feel better — and a lot of the evidence suggests it does not make much difference to tiredness, mood or sex drive. That does not mean nothing can be done. It means the answer is usually wider than a hormone shot: looking after your diabetes, weight, sleep and overall health matters a great deal.

Yes. Low testosterone is more common in men with type 2 diabetes than in men without it. It also becomes more common as men get older, and with extra body weight.

It mainly affects adult men. The risk is higher in men with type 2 diabetes, men carrying extra weight, men over about 40, and men with sleep apnoea, long-term illness, head injury or certain medicines. Boys can also have low testosterone, which can delay puberty.

Symptoms

Common symptoms

• Lower interest in sex than usual
• Trouble getting or keeping an erection
• Fewer morning erections
• Feeling tired all the time, even after a full night's sleep
• Low mood, irritability or feeling flat
• Losing muscle strength and putting on weight, especially around the belly
• Needing to shave less often, or less body hair
• Smaller testicles
• Hot flushes or sweats
• Weaker bones, so broken bones happen more easily

Causes

Main causes

• The testicles not making enough testosterone — the most common reason
• The brain signals that tell the testicles to work not working properly (problems with the pituitary gland or hypothalamus)
• Type 2 diabetes and extra body fat, which can lower testosterone levels
• Getting older
• Some medicines, long-term steroid tablets, strong painkillers such as opioids, and treatments like chemotherapy or radiotherapy
• Injury, infection or surgery affecting the testicles
• Heavy drinking over a long period

Risk factors

• Type 2 diabetes or metabolic syndrome (a cluster of problems including high blood pressure and high blood sugar)
• Carrying extra weight around the waist
• Being over 40
• Sleep apnoea (loud snoring with pauses in breathing during sleep)
• Long-term illness or ongoing stress
• Head injury or pituitary problems
• Heavy, long-term alcohol use
• Anabolic steroid use for bodybuilding

When to see a doctor

See a doctor urgently if:

• You have a painful, swollen or red leg
• You get a sudden severe headache or changes in vision
• You notice a new lump or tenderness in the breast area
• You feel very unwell with a high fever
• You have started hormone treatment and feel chest pain or breathless

Book a routine appointment if:

• Your sex drive has dropped and it bothers you
• You have erection problems
• You feel exhausted for weeks despite sleeping
• You feel low, flat or irritable much of the time
• You are thinking about testosterone treatment, or have been offered it
• You have diabetes and feel unusually tired or weak

Diagnosis

Your doctor will ask about your symptoms, sleep, mood, medicines, alcohol and sex life, and will examine you. They will then arrange a blood test. Testosterone is highest in the morning, so the test is usually taken before about 11am, and repeated on a second day to confirm the result before any decisions are made.

Tests that may be done

• A morning blood test for testosterone, usually repeated on another day
• Blood tests for other hormones from the pituitary gland
• HbA1c (your average blood sugar over about three months) and cholesterol checks
• A full blood count to check your red blood cells and iron levels
• A bone density scan if low testosterone has been present for a long time
• A sleep study if sleep apnoea is suspected

What to expect at your appointment

Blood test results usually come back within days to a couple of weeks. If just one test is low, your doctor will normally repeat it — levels can vary from day to day, and one reading is not enough to base treatment on. You should expect a conversation about your overall health, not just a single number.

Treatment

Treatment depends on the cause and on your symptoms. For many men with diabetes, the biggest improvements come from getting blood sugar into a healthier range, losing some weight, being more active, treating sleep apnoea and cutting back on alcohol. Replacing testosterone is an option for some men with clearly low levels and clear symptoms — but research in men with diabetes has found it does not reliably improve energy, mood or sexual function, so it is not a quick fix. Your doctor will talk through the possible benefits and risks with you.

Self-care at home

• Aim for regular sleep and a steady bedtime — testosterone is largely made during sleep
• Build activity into your day, including some strength work like carrying, gardening or resistance bands
• Try to lose a modest amount of weight if you carry it around the middle; even a small loss can help
• Cut back on alcohol, which lowers testosterone
• Ask about a sleep apnoea check if you snore heavily or wake unrefreshed
• Review your medicines with your doctor or pharmacist — some can affect hormones
• Keep up your diabetes checks, including blood pressure and cholesterol
• Avoid anabolic steroids bought for bodybuilding — they can shut down your own testosterone production

Medical treatments

Treatment may include tackling the underlying cause, such as sleep apnoea or a medicine that is affecting your hormones. For men with confirmed low testosterone and clear symptoms, replacing the hormone is an option — usually through the skin as a gel or patch, or by injection — with blood tests to check levels and red blood cells along the way. Other problems, such as erection difficulties or low mood, can be treated in their own right. All treatments have benefits and risks, and need follow-up. Never start hormones bought online or passed on by a friend; speak to your doctor or pharmacist first.

When is surgery considered?

Surgery is rarely needed. It may sometimes be considered for a specific cause, such as a pituitary tumour, or for swollen veins in the scrotum if that is found to be the reason for low testosterone.

Living with this condition

Low testosterone and diabetes affect each other, so looking after one helps the other. Focus on the basics that make the biggest difference: steady blood sugar, decent sleep, movement you enjoy, and honest conversations with your doctor about how you feel. Keep a simple note of symptoms so you can see changes over time rather than judging by a single bad week.

Lifestyle tips

• Move most days — walking, cycling, swimming, housework or gardening all count
• Add some strength work twice a week to protect muscle and bone
• Protect your sleep: regular hours, less screen time late at night, and limit alcohol in the evening
• Manage stress where you can — talking, breathing exercises, or time outdoors
• Stop smoking if you smoke; ask your local stop-smoking service for help
• Keep to your diabetes reviews, eye checks and foot checks

Diet and exercise

There is no special 'testosterone diet', but eating well helps your hormones, weight and blood sugar. Build meals around vegetables, beans, lentils, whole grains, fish, eggs and lean meat, and cut back on sugary drinks and heavily processed snacks. Regular activity — including brisk walking and some resistance work — helps your body use insulin better, protects muscle and bone, lifts mood and supports a healthy weight. Aim for something sustainable rather than extreme.

Mental health and emotional wellbeing

Low sex drive, tiredness and erection problems can knock confidence and strain relationships. Low mood is common and treatable, and it is not a sign of weakness. If you feel low, anxious or hopeless, tell your doctor — talking therapies and support are available. If you ever have thoughts of harming yourself, contact your local emergency number or a crisis line straight away, or go to the nearest emergency department. You deserve help right away.

Prevention

Not all cases can be prevented — some are caused by problems with the testicles or pituitary gland that cannot be avoided. But you can lower your risk and support your hormones by keeping to a healthy weight, staying active, sleeping well, limiting alcohol, not using anabolic steroids, and keeping your blood sugar, blood pressure and cholesterol in a healthier range.

Screening programmes

There is no routine screening programme for low testosterone. If you have type 2 diabetes and notice symptoms such as low sex drive, tiredness or erection problems, ask your doctor whether a morning blood test is appropriate.

Complications

If left untreated

• Thinning bones and a higher chance of fractures
• Loss of muscle strength and more body fat
• Ongoing low mood or depression
• Strain on relationships and confidence
• Low sex drive and erection problems continuing
• Anaemia (low red blood cells) in some men
• Poorer blood sugar control, as low testosterone and diabetes tend to worsen each other

Long-term outlook

The picture is more hopeful than a single headline suggests. While testosterone treatment alone may not be the answer for men with diabetes, there is a lot you and your doctor can do together: better sleep, gradual weight loss, activity, treating sleep apnoea, reviewing medicines and looking after your mental health. Many men feel noticeably better within a few months of making these changes, and support is available along the way.
