Symptoms of Hormone Imbalance for Men

By D Swain

Hormone imbalance is a common problem thatmany men face today. Some start showingsymptoms of hormone imbalance at the age of40.

This imbalance is usually caused by low levelsof testosterone because the production of allmale hormones decrease as a result of aging.

Breast Enlargement

One of the first symptoms of hormoneimbalance is an enlargement of the breasts.

This occurs mostly in men who have excessweight around the stomach because theyproduce more of an enzyme called aromatase.

This enzyme is responsible for convertingtestosterone into estrogens.

When too much estrogen is produced, it willlead to breast enlargement..

Erectile Dysfunction

Another one of the symptoms of hormone

imbalance in men is erectile dysfunction. Testosterone is needed to trigger a response in the

brain and also to produce and keep an erection.

When testosterone levels drop too low, it will take

longer to have an erection. The penis can even shrinkdue to low levels of

testosterone.

Muscle/Bone Loss

Reduced muscle and bone mass is also one of the

symptoms of hormone imbalance. Testosterone is also responsible for building

muscles and bone.

When levels are too low, loss of muscle and bone

mass is usually the result. In addition to this bone and muscle loss, many

men start to gain weight.

This press release issued by Eurekalertsays that the "raging hormones" of puberty..

are known to produce mood swings andstress for most teenagers,

..making it difficult to cope with thisperiod of life.

Are ductless gland

Secrete chemical signals (called hormones)

Directly into the blood

To control processes at another part of the body known as

Target cells or organs

E.g. Pancreas insulin & glucagon to liver & muscles

Ovaries - secrete oestrogen to uterus &

HmmWhats the difference b/w

endo & exocrine gland?Compare with:

Exocrine glands which have duct or secrete

chemicals via tubes, and Not into the blood, but to the external

environment

E.g. tear gland (eye) secretes tears

salivary gland (mouth) secretes saliva ,sweat gland (skin) produce sweat

sebaceous gland (skin) produce sebum

Pituitary glandPlays an important role as a

controller. It secretes anumber of hormones,

which control the functions

of several other endocrine

glands. This is why the

pituitary gland is often

referred to as the master

gland. The pituitary glandalso secretes antidiuretic

hormone (ADH).

15.1 Hormones

Definition ofHormones: [2m]

they are chemical substances,

- produced by endocrine glands,- transported by the bloodstream,

- to alter activities at the target organs

- Effective even in minute quantities

Hormones are converted to less active compoundsby the liver and destroyed by liver and excretedby the kidney

15.1 Hormones

Characteristics of Hormones: [3 m]

May have a controller E.g Master gland

(Pituitary gland)

May not function till a certain age

May have either short-term, *e.g. adrenaline for

fear

or long-term effect, *e.g. thyroxine for growth Production isbalanced and adequate;

*(lack produces some deficiency diseases; excess

production may be harmful)

24/55

Acts very quickly and has short-term action

Stimulus:Positive and negative stress,

excitement and fear

Receptor: Causes hypothalamus to activate

adrenal gland, message travels via nerves

15.1 Hormones a) Adrenaline

How the adrenal medulla responds to stimuli ?


26/55

Corrective Mechanism:

Effects ofadrenaline [4m]4b. To Increase blood

glucose concentration

4a. But also needs to stimulate

breakdown of glycogen to glucose in

muscles

3. More oxygen enables increasein metabolic rate in muscles:

Respiration for energy

1. Increased heart rate:

pump more oxygen to

muscles

6. Vaso-constriction of arterioles : skin

becomes pale as more blood goes to

internal muscles and vital organs

8. Increased blood coagulation

rate: in case of injuries/wounds

2. Increased breathing rate

in the lungs for more

oxygen

7. Increased eye

(pupil) dilation

Muscle tension can cause Goose-pimples: hair stands!
